| Abstract: | Right turbulent model is important for availably numerical simulation of the jet impinging heat transfer. This paper simulate gas jet impingement of the big diameter and the high velocity and temperature with the standard k-ε, modeI,RNG k-ε, model and Realizable k-ε model. The numerical result has been compared with the experiment results. The applicability of the turbulent model has been analyzed in the numerical simulation of the big diameter jet impingement. The result has offered the reference for the big diameter jet impinging in numerical study. |
