Description
Summary:In this paper, vibrations of micropolar membranes in contact with fluid are investigated. The fluid is assumed to be incompressible and contained in a cube and the only non-rigid lateral face is made of a flexible micropolar membrane and interacts with the fluid. The Chebyshev–Ritz polynomials are adopted to attain the dry and wet frequencies of the membranes. The microrotational frequencies evaluated in the present study are also compared with those from the analytical solutions. This comparison shows that the differences between the calculated frequencies and analytical ones are negligible.
