Simulation On Non-linear Solid-fluid Coupling Of Multi-pore Structures Based On Plane Collagen Scaffold

It has been proved by the research of recent several dozens of years that,biological tissue's porous configurations and situations biology betwteen mechanics in this living system together directly or indirectly influence the basic research of mechanics regulation mechanism, which is the advanced question of biological mechanics. Therefore, the interaction of the biological tissue or support porous configuration and matrix, cell and environmental factor in the system, as well as the research on porous biography has the important theory and the application values on understanding the real clinical pathology and the real biological tissue mechanics regulation mechanism.Based on the theory of large solid deformation, the thesis verifies the précising and relying proprieties of the large deformation mechanical model and on the foundation of Navier-stokes equations, it proofs the précising and relying solution on stabilization layer flowing.Using non-linear coupling method to solve the non-linear problem of flow-field and structure, finding the solutions separately on field of flow and structure, then calling interface program of ANSYS and FLUENT, coupling time steps of flow-field and structure, propelling after convergence, we will get convergence solutions. This thesis is obtained multi- pore numerical calculation of different fluent medias in the cellular supporting plane containing arc, rectangular, and triangle configurations, and derives some results assuming reference values, then discusses based on the computing results and generalizes some regularity.
