Numerical Study on Radiation-Convection Heat Transfer

摘要

In this study, the authors attempted a simualtion tehcnique of radiatin-convection heat transfer in the high tmperature fields of industrial furnaces, biolers and gas turbine comustors. The covnection effect is analyzed by differential equatins, but the radiation effect is analyzed by an integral equation. S, both effects are difficult to arrange using the same type of equation. Then, the authors introduced the Zone Method and Monte Carlo Method for integral equation of radiation effect and the Finite Differrence Method for differential equatins of convection efect. A three-dimensional analysis of a high temperature furnace was performed by this simulation tehcnique to obtain its temperature distributin. 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 radiatin-conection heat transfer, and described their idea of sofltware constrution for the above.
