Propagation characteristics in distensible tubes containing a dusty viscous fluid (Q1108896)

The authors have studied the problem of a dusty viscous fluid in distensible vessel, using the vessel as a straight thin-walled circular distensible tube, which is assumed to be constricted externally to ignore the longitudinal movement. The governing equations of motion and the components of velocity of the fluid and the dust particles are given. Results are analyzed for the resistence and the reactance of the fluid and wall impedance. The influence of dust particles on these factors is noted and observation made in reference to the presence of the high haemoglobin contents in blood.
