| Abstract: | The need for numerical simulating conjugated heat transfer with complex intra-face is recognized. Because of the complex intra-face, the normal approaches have difficulties in solving such problems. An auto-adaptive Cartesian grid method approach to tackle the complex intra-face is developed. An auto-adaptive Cartesian grid generator and 3D viscous convection flow solver have been developed and applied to solve two flow problems. |
