A note on turbulent energy dissipation in the viscous wall region

From simulation data it is shown that the difference between the true rate of dissipation of turbulent kinetic energy and the ‘‘isotropic dissipation’’ used by Reynolds‐averaged modelers is less than 2% in a conventional viscous wall region, and negligible elsewhere. The difference is a contribution to viscous diffusion which is a small fraction of the total.

关于粘性壁区域湍流能量耗散的注意事项

从仿真数据可以看出,在常规方法中,湍动能的真实耗散率与Reynolds平均建模者使用的“各向同性耗散”之间的差异小于2%。 粘性的墙区域,其他地方微不足道。区别在于粘性的 扩散 这只是总数的一小部分。
