Outline of Final Research Achievements

In this study, our proposed multiphase computational method for thermal interactions between solids and compressible fluids was improved to consider the differences of physical properties between phases and the movement of the solid object. The mixture model was adopted in the proposed method, and the phase-averaged governing equations for multiphase fields, which are derived on the basis of the volume fractions of the phases in each computational cell, are solved by a compressible fluid solver which can be applied to non-isothermal low Mach number flows. The validity of the phase-averaging method was confirmed through the comparisons with the calculated results by the computational method which treats fluid and solid phases individually. In addition, the proposed method was applied to the heat transfer around a rotating gear-shaped solid object and its applicability was shown.
