Abstract:Fluid-solid coupling mechanics is an interdisciplinary branch with various different formulations in the academic circles. According to the normal formulations and the understandings in a narrow sense, the main task of fluid-solid coupling mechanics is to study the dynamic properties of the interaction of fluid and solid elasticity. Turbomachinery provides an important engineering background to the fluid-solid coupling mechanics. The research on fluid-solid coupling of turbomachinery is also a major part ...
