Moving computational multi-domain method for modelling the flow interaction of multiple moving objects

Abstract This study proposes a method for modelling the flow interaction of multiple moving objects where field variables are communicated between separate computational domains. Instead using conventional approach with single fixed domain covering whole field, this advances (MCD) in which itself moves line motions an object inside. The domains created around each move independently, and fields interact flows cross. eliminates spatial restriction simulating objects. Firstly, shock tube test verifies that overset implementation grid movement do not adversely affect results there is communication grids. A second case conducted two spheres crossed, forces exerted on one due to other’s crossing at short distance calculated. verify reliability show it applicable
