Experimental setup for generation and control of sinusoidal pulsatile channel flow

A scheme of an experimental setup for generation and control of sinusoidal pulsatile channel flow has been presented. A pulsator with the shaped rotating flap ensured a cross section area variation by harmonic law is used. Based on the solution of Bernoulli's unsteady equation and the numerical solution of the URANS equations, the effect of inertia forces on the law of average velocity variation over the pulsation phase in the test section of the experimental setup has been estimated.
