摘要
A numerical method is developed for solving three-dimensional, unsteady, incompressible flows with immersed moving solids of arbitrary geometric complexity. A co-located (nonstaggered) pressure-based finite-volume method is employed to solve the Navier-Stokes equations for the flow region, and the solid region is represented by material points with known position and velocity. The influence of the body on the flow is accounted for by reconstructing implicitly the velocity on the immersed boundary faces b-tween fluid and solid. Canonical test cases and mesh convergence tests are carried out. A validation test for the vibration of microcantilevers shows good agreement between computed and measured damping factor values.
