Flow Simulations on Cartesian Grids involving Complex Moving Geometries

چکیده
We describe a method to solve the compressible time-dependent Euler equations using Cartesian grids for domains involving xed or moving geometries. We describe the concept of a mirror ow extrapolation of a given solution over a reeecting wall which may be curved or moving at a xed or varying speed. We use this mirror ow to develop a Cartesian grid method to treat the cells along a reeecting boundary avoiding the \small-cell" problem. Numerical Results are presented.

Parallel large-eddy simulations of turbulent flows with complex moving boundaries on fixed Cartesian grids
A parallel embedded boundary approach for large-eddy simulations of turbulent flows with complex geometries and dynamically moving boundaries on fixed orthogonal grids is presented. The underlying solver is based on a second-order fractional step method on a staggered grid. The boundary conditions on an arbitrary immersed interface are satisfied via second-order local reconstructions. The paral...
متن کاملRobust and Efficient Setup Procedure for Complex Triangulations in Immersed Boundary Simulations
Immersed boundary methods have been widely used for simulating flows with complex geometries, as quality boundaryconforming grids are usually difficult to generate for complex geometries, especially, when motion and/or deformation is involved. Complex geometries can be conveniently represented using triangulated surfaces in a Lagrangian manner. A major task in immersed boundary simulations is t...
متن کاملAn Overset Adaptive Cartesian/Prism Grid Method for Moving Boundary Flow Problems
The use of overset grids in CFD started more than two decades ago, and has achieved tremendous success in handling complex geometries. In particular, overset grids have the advantage of avoiding grid remeshing when dealing with moving boundary flow problems. Traditionally overset grids were mainly used with structured grids to simplify the grid generation process, because a complex computationa...
متن کاملMultiphase Dynamics in Arbitrary Geometries on Fixed Cartesian Grids
In this work, a mixed Eulerian–Lagrangian algorithm, called ELAFINT (Eulerian Lagrangian algorithm for interface tracking) is developed further and applied to compute flows with solid–fluid and fluid–fluid interfaces. The method is capable of handling fluid flows in the presence of both irregularly shaped solid boundaries and moving boundaries on a fixed Cartesian grid. The field equations are ...
متن کاملAnalysis of Flying and Swimming in Nature Using an Immersed Boundary Method
he last decade has seen a tremendous rise in the popularity of immersed boundary methods [1-6] . The primary factor driving this is the relative ease with which this methodology allows researchers to develop computational models of flows with complex geometries and/or moving boundaries. Immersed boundary solvers have been employed successfully for simulating biological flows, physiological flow...
