Summary: | In the article we consider the flow of viscous compressible fluid in a channel with oscillating walls. The obtained solutions of linearized Navier–Stokes equations suggest that resonance phenomena are possible under certain conditions, namely, under the particular relation between the frequency of wall vibration, the geometrical characteristics of a channel and speed of sound in the fluid. Resonance phenomena result in the periodical changes of flow parameters with maximum amplitude. The numerical simulations based on full Navier–Stokes equations show that great increase in the mass rate of the flow can occur even if fluid is pumped at constant pressure gradient. |
