摘要
采用标准k-ε模型、RNG模型、可实现k-ε模型对气流横向冲刷管束换热进行模拟计算。结果表明,在Re<10000,都可以得到比较可靠的预测结果;但在Re>10000,标准k-ε模型与RNG k-ε模型都不再适用,而可实现k-ε模型可以获得比较可靠的预测结果。
Simulation calculation of heat transfer of air flow across has been completed using standard k-ε model, RNG model and Realizable k-ε model. Tbe results showed that Reliable prediction results can be got in condition of Re〈 10000, but standard k-ε model and RNG model are no longer applicable and only Realizable k-ε model can be used. in condition of Re〉 10000.
