Additional effects of uid on the piston

Abstract

Additional eect of uid on the solid body is often ignored phenomenon. Although it is possible to do an analytic derivation of equations describing additional eects for many various conditions, it can be dicult to solve them. The paper shows pressure pulsations in the pipe with piston solved by transfer matrix and harmonic analysis with ANSYS Acoustics, where eect of second viscosity is included.Additional eect of uid on the solid body is often ignored phenomenon.
