<p>The flow of a frictional, cohesive solid through plane converging
channels with Coulomb friction acting along the channel walls is
investigated. The constitutive postulates used in the development of
the solution are discussed and the solution is compared with those obtained
by earlier investigators. Velocity profiles, mass flow rates,
and mean stress distributions along the channel walls predicted by the
analysis are compared with experimental results. The solution correctly
predicts the trend of the mass flow rate as a function of the
channel opening angle as well as the magnitude of the mass flow rate in
terms of the flow parameters. The solution also gives an accurate
measure of the mean stress acting along the channel walls.</p>
<p>The problem of predicting the size of the cavity formed below
a cylinder in the transverse flow of a frictional, cohesionless material
is investigated experimentally. A correlation which gives the lower
separation angle as a function of the flow parameters is determined.</p>
<p>Finally, the temperature distribution in the wake of a heated
cylinder in the transverse flow of a granular material is investigated
experimentally and spanwise temperature profiles are given as a
function of downstream location.</p>
<p>The information gained from the experimental investigation is
intended to be of use in the design of heat exchanger equipment for
granular media.</p>https://thesis.library.caltech.edu/id/eprint/10131
