Numerical simulation of cross-flow around four cylinders by Local Domain Free Discretization-Immersed Boundary Method

Abstract

In this paper, a hybrid of Local Domain Free Discretization and Immersed Boundary Method (termed as LDFD-IBM), is applied to simulate the incompressible flow over four circular cylinders in an in-line square configuration. LDFD-IBM belongs to the family of "Cartesian mesh methods", which means the complication of mesh generation is avoided for the problems with complex geometries. A Stencil Adaptive Mesh Refinement (SAMR) is also adopted to improve the computational efficiency. Instantaneous flow patterns and other quantitative information from the numerical simulation agree well with the available data from literatures.
