Numerical Simulation of Flow around Sphere

Abstract

In this study, The three dimensional flow past a sphere and a rotating sphere with smooth surface in a uniform stream is calculated by the finite element method with the fractional step method and the balancing tensor difusivity method. At the high Reynolds number Re≥1.0×(10)^4,we analyze that flow using Large Eddy Simulation. Turbulent model is the Smagorinsky model. As a result, the agreement with experiment and the flow visualization was reasonable up to reynolds number 500.
