Rotating flows with heat transfer are encountered in many engineering-relevant applications such as in turbomachinery. However, it is no easy matter to make fine measurements of rotating flows with heat transfer. As an alterative, a direct numerical simulation (DNS) has been utilized to examine canonical rotating flows. and turbulence models have been used for predicting realistic rotating flows. In the present study, to construct a turbulence model for heat transfer in rotating wall-bounded flows, we have modeled the expression for turbulent heat-flux so as to contain Coriolis effects. The proposed nonlinear two-equation heat-transfer model can properly predict rotating flows with heat transfer, though the assessment of the existing nonlinear two-equation heat-transfer models indicates marked disagreement with the DNS provided in this series of studies.
