Solving Fluid/Rigid Body Interaction Problem by A Cartesian Interface Method

摘要：

Fluid-rigid body interaction problems are solved by a novel fixed uniform mesh approach which use a level set function to implicitly track the fluid-rigid interface. The interface boundary conditions are also captured implicitly by combing a Ghost Fluid method with level set method. A reflective boundary condition is used to populate the ghost cells and the resulting heating errors are corrected by employing isobaric fix technique. This approach can be easily extended to three dimensional questions since no mesh motion or modification is required. It also has the applicability for problems with complex object motion and complex geometry. The method has been shown with several two dimensional examples to successfully simulate the fluid/rigid body interaction problems.
