Application of auto-adaptive Cartesian grid approach to numerical simulation of convection

It is difficult to deal with complex geometric regions for numerical simulation of convections. The auto-adaptive Cartesian grid approach is able to tackle the problem easily. But, up to now, it is mainly applied to solving compressible outer flows of Euler equations and Navier-Stokes equations. This paper simulated two convection cases of incompressible inner flow. The two cases were also simulated by STAR-CD, a commercial CFD code. The simulation results by auto-adaptive Cartesian grid approach and STAR-CD were compared and consistencies were shown. So the auto-adaptive Cartesian grid approach is suitable to be applied to simulating convection problems.
