| Research Abstract |
Compressive CFD analysis of multiple material system was carried out for the kettle experiment using IH cooking heater, and the prediction accuracy was sharply improved for the flow and temperature fields as compared with the usual incompressible CFD analysis. In the case study of CFD analysis, the analysis in consideration of (1) steam generating in water surface and (2) air density change by the change of temperature and humidity was performed, especially, about the evaluation of flow field of pan right above, the influence of modeling of (1) was large, and the influence of (2) was larger in evaluation of temperature field of pan right above conversely.
