Abstract

The results of a numerical calculation by the RANS method of a separated flow in a planar channel in the presence of a honeycomb surface are presented. The calculation is performed for Reynolds numbers ( \( 14\thinspace 000\leqslant \mathrm {Re}\leqslant 28\thinspace 000 \)) determined from the average mass velocity and channel height. The distribution of the local Nusselt number is obtained for various Reynolds numbers and cell depths. It is shown that the distribution of the Nusselt number on the surface is highly nonuniform; in particular, the maximum heat transfer is observed near the upper face of the ribs, in the vicinity of which the largest velocity gradient is observed.

变深度六角形蜂窝平面通道内紊流与换热结构的数值研究

本文给出了蜂窝面存在时平面通道内分离流动的RANS数值计算结果。计算执行雷诺数(\( 14\thinspace 000\leqslant \mathrm {Re}\leqslant 28\thinspace 000 \))由平均质量速度和通道高度确定。得到了不同雷诺数和单元深度下的局部努塞尔数分布。结果表明，表面上的努塞尔数分布极不均匀;特别是，在肋的上表面附近观察到最大的换热，在其附近观察到最大的速度梯度。
