Study on adaptive mesh generation method in CFD calculation with conjugate heat transfer model

In order to make proper radiative meshes with considering thermal distribution on solid surfaces, we inves- tigated the adaptive mesh generation method and per- formed parametric survey for a threshold which con- trols subdivision of mesh. With these studies we found that the adaptive mesh generation increase the accu- racy of predicting mesh surface temperature and air temperature even if the adaptive subdivision is rather soft one. We performed the transient simulation during eight hours after the air-cooling system’s breakdown with the mesh generated by the middle adaptive sub- division and compared with the experiment data. As a result the overall agreement between the two was good enough for our practical use.
