A numerical simulation of the T-junction channel flow with heat transfer has been carried out in order to investigate and observe a phenomenon of turbulent heat transfer and a turbulent mixing of temperature, in which a numerical simulation is conducted by using DNS method. In results of DNS, the detailed turbulent heat transfer and a turbulent mixing of temperature in T-junction are clearly given. Also, two conditions of thermal field at inlet channels are given in order to observe the influences of thermal inlet condition, i.e., a uniform temperature without temperature fluctuation or a non-uniform temperature with temperature fluctuation is given at the inlet channel. In the results, differences of heat-transfer and turbulent mixing of temperature at the separation region of T-junction are revealed. On the other hand, a large eddy simulation of T-junction channel is also carried out in order to evaluate predictions of LES and investigate a T-junction flow with higher Reynolds number.
