The tube contains a rigid body (particle), and the plane standing acoustic is presented in the tube. Aims of the work are investigation of the hydrodynamic characteristics of the system consisting of the infinite thin cylindrical tube with compliant elastic walls filled with the liquid and rigid cylindrical body located on the tube axis; calculation of the acoustic field pressure in the system; determination of the acoustic hydrodynamic force acting on the particle and calculation of the acoustic radiation force by the time averaging of the hydrodynamic force derived; investigation of the influence of standing wave frequency, density of the liquid and speed of the sound in it as well as spherical particle radius and elastic properties of the tube material on the acoustic radiation force behavior. Investigation methods are the analytical methods of mechanics. Statement of the problem on the acoustic pressure and acoustic radiation force determination for the particle in the thin elastic tube is formulated for the case of standing wave. Expression for the acoustic radiation force acting on the particle is derived. Regularities of the pressure field and acoustic radiation force behavior are studied depending on the standing wave frequency, material properties of the compliant tube, thickness of the tube wall, properties of the filling liquid and spherical particle radius  Product Description popup.authors popup.nrat_date 2022-03-09 Close
