title: Note on wave propagation in a thin elastic tube containing a viscous fluid.
abstract: This paper deals with the theoretical and experimental investigation of the propagation of pressure waves through a straight thin-walled elastic tube, filled with a streaming Newtonian fluid. The tube used was of silicon rubber and measured 200 mm in length, 8 mm in internal diameter and 1 mm in wall thickness. The velocity profiles across the diameter of the tube were measured at the beginning, at the middle and the end of the elastic pipe and compared with the results of a mathematical-computational model. The test data agree fairly well with the calculated values.
