摘　　要：文章基于FLUENT软件,首先采用SSTk-ω湍流模型,对单孔冲击射流在有横流和无横流两种情况下的换热特性进行了数值模拟,获得了被冷却面的Nu分布规律;然后将计算结果与Goldste in&Behbahan i公开的实验结果作了比较。通过比较发现,数值计算结果与实验结果吻合良好。Based on FLUENT software, firstly, the SST k -ω turbulence model is adopted in the numerical investigation for the single jet impinging with and without a crossflow, then the Nusselt number distribution characteristics of the target face are obtained. Compu- tational results are compared to experimental data available from the open literature of Goldstein ＆ Behbahani. The comparison results indicate that the numerical results show a good agreement with the experimental reference data. So, we can say that the SST k - ω turbulence model have significant reliability in the investigation of heat transfer in the impinging jet.
