对于不可压缩湍流与大雷诺数和Peclet数，在大波数的动能，热量和质量的光谱传输的机制提出。基于这些机制，湍流能量，温度和浓度谱函数推导出整个普适平衡波数范围。将所得的一维能量、温度和浓度谱与测量结果进行比较。
For incompressible turbulent flow with large Reynolds and Peclet numbers, mechanisms for the spectral transfer of kinetic energy, heat, and mass at large wavenumbers are proposed. Based on these mechanisms, turbulent energy, temperature, and the concentration spectrum functions are deduced for the entire universal equilibrium range of wavenumbers. The resulting one‐dimensional energy, temperature, and concentration spectra are compared with measurements.
