Numerical study on radiation-convection heat transfer

In this study, the authors attempted a simulation technique of radiation convection heat transfer in the high temperature fields of industrial furnaces, boilers and gas turbine combustors. The convection effect is analyzed by differential equations, but the radiation effect is analyzed by an integral equation. So, both effects are difficult to arrange using the same type of equations. Then. the authors introduced the Zone Method and Monte Carlo Method for integral equation of radiation effect and the Finite Difference Method for differential equations of convection effect. A three-dimensional analysis of a high temperature furnace was performed by this simulation technique to obtain its temperature distribution. Furthermore, another radiation-convection heat transfer analysis in a low temperature living room was performed by the same technique. Finally, the authors tried to develop computer software for radiation convection heat transfer, and described their idea of software construction for the above.
