Experimental analysis of steady and pulsating flows in collapsible walls
An experimental set-up to measure the changes of geometry of elastic walls and input and output pressures for constant and pulsating flow reflecting blood flow in human arteries was designed, built and tested. The paper presents the results of extensive experiments of static and pulsating flow parameters as functions of flow rates and pulsation frequencies for various properties of tested tubes. Aperiodic time series of pressure due to occurrence of turbulent flow have been observed.
