| Abstract: | A 3-D wave model for the turbulent coherent structures in near-wall region is proposed. The transport nature of the Reynolds
stresses and dissipation rate of the turbulence kinetic energy are shown via computation based on the theoretical model. The
mean velocity profile is also computed by using the same theoretical model. The theoretical results are in good agreement
with those found from DNS, indicating that the theoretical model proposed can correctly describe the physical mechanism of
turbulence in near wall region and it thus possibly opens a new way for turbulence modeling in this region. |
