Several characteristics observed experimentally and also present in the model response are discussed.</p>\r\n\r\n<p>The resultant model's capability for predicting structural response for a wide range of fluid mediums is illustrated through comparisons between model predictions and results obtained experimentally from flexibly-mounted cylinders in air and in water.</p>\r\n\r\n<p>This model developed is expected to yield better results for structures in water, by virtue of being based only on experimental results obtained in water.</p>",
