A technical summary of work completed under contract N00014-06-1-0299, entitled Human Bioresponse to Low-Frequency Underwater Sound, is given. Preliminary research such as the development of two micromechanical models of lung tissue and the calculation of elastic constants based upon such models is described. Progress made in the development of a lumped-element model of the human body and its internal organs is discussed. Master's theses completed under this contract are attached. ...
For high gas supersaturation levels in liquids, on the order of 300% as predicted in capillaries of marine mammals following a series of dives, standard mathematical models of both static and rectified diffusion are found to underestimate the rate of bubble growth by 10%-20%. The discrepancy is demonstrated by comparing predictions based on existing mathematical models with direct numerical solutions of the differential equations for gas diffusion in the liquid ...
Many theories describing cavitation noise model the phenomenon by considering the independent annihilation of cavities in an infinite fluid. Since most practical applications involve cavitation generated by the dynamical action of flow, it is valuable to know how these theories will compare with such experimental data. In this investigation, a Schiebe body is employed as a headform that supports travelling bubble cavitation which is analyzed with regard to the various ...
