摘要 An accurate cartesian method is devised to simulate incompressible viscous flows past an arbitrary moving body.The Navier-Stokes equations are spatially discretized onto a fixed Cartesian mesh.The body is taken into account via the ghost-cell method and the so-called penalty method,resulting in second-order accuracy in velocity.The accuracy and the efficiency of the solver are tested through two-dimensional reference simulations.To show the versatility of this scheme we simulate a threedimensional self propelled jellyfish prototype.
