Multiphysics analysis for fluid-structure interaction of flexible baffle inside wavy cavity with slipping wall

Abstract

The development of methods for making fluids in a state of turbulence to obtain better heat transfer and its strong effect on the elastic wall. One of the ways that we can obtain the turbulent state of the fluid is to make one of the surfaces of the solid slide at a certain speed. This slip leads to the surface tension in a state of turbulence, and this rotates the fluid flow in a way large and in order to obtain better turbulence, it is used to make the surfaces surrounding the fluid in a directional way to help rotate the fluid. The results proved the effectiveness of this stereotype, as the force of the effect of the fluid velocity on the elastic wall was in the case of the thickness of 0.5 mm and the sliding velocity of 0.9 m/s, where the deformation was 5.6 mm, which is the best strike condition was deduced either at 2 mm thickness and 0.1 m/s sliding velocity where the deformation was 0.272 mm which is the least deformation reached by the wall.
