Procedure for Nonlinear Oscillations: The Dynamics of Two Oscillators with Weak Nonlinear Coupling", "ispublished": "unpub", "full_text_status": "public", "keywords": "Physics", "abstract": "
This thesis considers in detail the dynamics of two oscillators with weak nonlinear coupling. There are three classes of such problems: non-resonant, where the Poincar\u00e9 procedure is valid to the order considered; weakly resonant, where the Poincar\u00e9 procedure breaks down because small divisors appear (but do not affect the O(1) term)\r\nand strongly resonant, where small divisors appear and lead to O(1) corrections. A perturbation method based on Cole's two-timing procedure is introduced. It avoids the small divisor problem in a straightforward manner, gives accurate answers which are valid for long times, and appears capable of handling all three types of problems with no change in the basic approach.
\r\n\r\nOne example of each type is studied with the aid of this\r\nprocedure: for the nonresonant case the answer is equivalent to the Poincar\u00e9 result; for the weakly resonant case the analytic form of the answer is found to depend (smoothly) on the difference between the initial energies of the two oscillators; for the strongly resonant case\r\nwe find that the amplitudes of the two oscillators vary slowly with time as elliptic functions of \u03f5 t, where \u03f5 is the (small) coupling parameter.
\r\n\r\nOur results suggest that, as one might expect, the dynamical behavior of such systems varies smoothly with changes in the ratio of the fundamental frequencies of the two oscillators. Thus the pathological behavior of Whittaker's adelphic integrals as the frequency ratio is\r\nvaried appears to be due to the fact that Whittaker ignored the small divisor problem. The energy sharing properties of these systems appear to depend strongly on the initial conditions, so that the systems not ergodic.
\r\n\r\nThe perturbation procedure appears to be applicable to a wide variety of other problems in addition to those considered here.

Abstract is included in .pdf document.\n\nA systematic approach is given for finding similarity solutions to partial differential equations by the use of transformation groups.\n\nIf a one-parameter group of transformations leaves invariant a partial differential equation and its accompanying boundary conditions, then the number of variables can be reduced by one. In order to find the group of a given partial differential equation, the \"classical\" and \"non-classical\" methods are discussed. Initially no special boundary conditions are imposed since the invariances of the equation are used to find the general class of invariant boundary conditions.\n\nNew exact solutions to the heat equation are derived. In addition new exact solutions are found for the transition probability density function corresponding to a particular class of first order nonlinear stochastic differential equations. The equation of nonlinear heat conduction is considered from the classical point of view.\n\nThe conformal group in n \"space-like\" and m \"time-like\" dimensions, C(n, m), which is the group leaving invariant [...], is shown to be locally isomorphic to S O (n+l, m+l) for n + m >= 3. Thus locally compact operators, besides pure rotations, leave invariant Laplace's equation in n >= 3 dimensions. These are used to find closed bounded geometries for which the number of variables in Laplace's equation can be reduced.\n", "date": "1968", "date_type": "degree", "id_number": "CaltechETD:etd-04082005-155822", "refereed": "FALSE", "official_url": "https://resolver.caltech.edu/CaltechETD:etd-04082005-155822", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "collection": "CaltechTHESIS", "deposited_by": "Imported from ETD-db", "deposited_on": "2005-04-08", "doi": "10.7907/X1E8-1E61", "divisions": { "items": [ "div_eng" ] }, "institution": "California Institute of Technology", "thesis_type": "phd", "thesis_advisor": { "items": [ { "id": "Lagerstrom-P-A", "name": { "family": "Lagerstrom", "given": "Paco A." }, "role": "advisor" }, { "id": "Cole-J-D", "name": { "family": "Cole", "given": "Julian D." }, "role": "advisor" } ] }, "thesis_committee": { "items": [ { "name": { "family": "Unknown", "given": "Unknown" } } ] }, "thesis_degree": "PHD", "thesis_degree_grantor": "California Institute of Technology", "thesis_submitted_date": "2005-04-08", "thesis_defense_date": "1967-11-14", "thesis_approved_date": "2005-04-08", "review_status": "approved", "option_major": { "items": [ "appliedmath" ] }, "copyright_statement": "I hereby certify that, if appropriate, I have obtained a written permission statement from the owner(s) of each third party copyrighted matter to be included in my thesis, dissertation, or project report, allowing distribution as specified below.

Abstract is included in .pdf document.\r\n\r\nPlane waves propagating in a perfectly electrically conducting polytropic gas of otherwise uniform state in the presence of an arbitrarily oriented uniform magnetic field are studied; they correspond to plane simple waves in magnetohydrodynamics. Riemann invariants across finite amplitude waves in ordinary gasdynamics are generalized herein to take into account all possible magnetohydrodynamics effects. There exist totally seven types of waves, namely, contact surfaces, forward and backward facing transverse simple waves and forward and backward facing coupled (fast and slow) simple waves. But of these only coupled waves are genuinely nonlinear and receive most of our attention. The mathematical theory of simple waves is discussed first to give a general picture of the underlying structure of solutions. Contact surfaces and transverse simple wave solutions are given next with particular emphasis on the case of the contact surface adjacent to a vacuum, region. An exact analytical solution of coupled waves for gases of arbitrary value of [...] is obtained in terms of generalized Riemann invariants; some of these invariants are expressed in terms of definite integrals of a parameter [...]. The invariant relations among several physical quantities are thus expressed in a parametric form. An alternative method of solving coupled waves by graphical means is proposed and some detailed calculations are presented. General properties of physical variables across coupled waves are mentioned.

First the expansion of a gas cloud into perfect vacuum is considered on the basis of the collision-less Boltzmann equation, and it is shown that if the initial distribution is an isothermal Maxwellian, the density obeys a diffusion equation with a diffusion coefficient proportional to the time. This leads to the description of the free expansion of symmetric clouds in terms of a thick 'diffusion front' traveling at the initial isothermal speed of sound. The expansion of asymmetric clouds and the flow due to sources and jets are also studied.\r\n\r\nSecond, a method of iteration proposed by Willis for calculating nearly free molecular flow is extended to general unsteady flows; it is then applied to the flow through an orifice to show that the correction to the mass flow is of the first order in the inverse Knudsen number. The coefficient, estimated by making some reasonable assumptions about the three-dimensional nature of the flow, is found to agree quite well with Liepmann's measurements.\r\n\r\nFinally a physical basis is suggested for Krook's collision model used in the above calculations. Several consequences of the model are then derived, including the important one that, in the Navier-Stokes limit, the model implies a Stokesian gas with a Prandtl number of unity. The value to be given to the parameter in the model is also discussed at some length.", "date": "1961", "date_type": "degree", "id_number": "CaltechETD:etd-11042003-095050", "refereed": "FALSE", "official_url": "https://resolver.caltech.edu/CaltechETD:etd-11042003-095050", "rights": "No commercial reproduction, distribution, display or performance rights in this work are provided.", "collection": "CaltechTHESIS", "reviewer": "Kathy Johnson", "local_group": { "items": [ "GALCIT" ] }, "deposited_by": "Imported from ETD-db", "deposited_on": "2003-11-04", "doi": "10.7907/1S8T-QA38", "divisions": { "items": [ "div_eng" ] }, "institution": "California Institute of Technology", "thesis_type": "phd", "thesis_advisor": { "items": [ { "id": "Liepmann-H-W", "name": { "family": "Liepmann", "given": "Hans Wolfgang" }, "role": "advisor" }, { "id": "Cole-J-D", "name": { "family": "Cole", "given": "Julian D." }, "role": "advisor" } ] }, "thesis_committee": { "items": [ { "name": { "family": "Unknown", "given": "Unknown" } } ] }, "thesis_degree": "PHD", "thesis_degree_grantor": "California Institute of Technology", "thesis_submitted_date": "2003-11-04", "thesis_defense_date": "1961-01-01", "thesis_approved_date": "2003-11-04", "review_status": "approved", "option_major": { "items": [ "aeronautics" ] }, "option_minor": { "items": [ "physics" ] }, "copyright_statement": "I hereby certify that, if appropriate, I have obtained a written permission statement from the owner(s) of each third party copyrighted matter to be included in my thesis, dissertation, or project report, allowing distribution as specified below.

Important features of exact equations of motion and their corresponding linearized equations are studied briefly. For this linear system, which preserves many of the features of the original non-linear system, the fundamental solutions are found and discussed. The additional role played by viscosity in the heat conduction problem is then investigated. The fundamental solutions for this compressible, viscous, heat-conducting flow problem are found and compared with the non-viscous case. The problem of heat conduction in a two-dimensional stationary flow of a viscous compressible fluid is further studied by finding the fundamental solutions and discussing the result in some detail. As an example proposed to show how a superposition of these fundamental solutions can be used to solve a boundary value problem, the problem of the anemometry of a heated flat plate is solved for both large and small values of the Reynolds number. The result obtained herein is discussed and compared with some existing theories and experiments.
