Logarithmic boundary layers have been observed in different regions in turbulence. However, how thermal plumes correlate to the log law of temperature and how the velocity profile changes with pressure gradient are no...
本文采用湍流热对流的并行直接数值模拟(Parallel Direct Method of Direct Numerical Simulation,PDM-DNS),计算了系列Ra数的二维方腔Rayleigh-Bénard热对流.选取典型Ra=10^(10),Pr=4.3,讨论了流动平均场的近底板区域温度分布.温度边...
