متن کاملA cartesian grid method for modeling multiple moving objects in 2D incompressible viscous flow
We present an efficient method for solving 2D incompressible viscous flows around multiple moving objects. Our method employs an underlying regular Cartesian grid to solve the system using a streamfunction–vorticity formulation and with discontinuities representing the embedded objects. The no-penentration condition for the moving geometry is satisfied by superposing a homogenous solution to th...
متن کاملA Projection Method for Incompressible Viscous Flow on a
A Projection Method for Incompressible Viscous Flow on a Deformable Domain by David Paul Trebotich Doctor of Philosophy in Mechanical Engineering University of California, Berkeley Professor Phillip Colella, Chair 1 A second-order accurate finite difference method is presented for numerical solution of the incompressible Navier-Stokes equations on a deformable domain. The target problem is flow...
متن کاملDivergence-free Wavelet Projection Method for Incompressible Viscous Flow
We present a new wavelet numerical scheme for the discretization of Navier-Stokes equations with physical boundary conditions. The temporal discretization of the method is inspired from the projection method. Helmholtz-Hodge decomposition using divergence-free and curl-free wavelet bases satisfying physical boundary conditions allows to define the projection operator. This avoids the use of Poi...
متن کاملAn Adaptive Mesh Projection Method for Viscous Incompressible Flow
Many uid ow problems of practical interest|particularly at high Reynolds num-ber|are characterized by small regions of complex and rapidly-varying uid motion surrounded by larger regions of relatively smooth ow. EEcient solution of such problems requires an adaptive mesh reenement capability to concentrate computational eeort where it is most needed. We present in this paper a fractional-step v...
