A discussion on finite-difference schemes for low Prandtl number ...
Webthat the Rayleigh-Bénard convection of low Prandtl number fluid is very sensitive to the numerical algorithm. As the Rayleigh number is larger than its critical value, the fluid begins to move and forms a steady flow pattern of two-dimensional rolls parallel to each other. For higher Rayleigh number the rolls become unsteady and the bending of WebDec 18, 2024 · 1.2 Rayleigh-Bnard 对流研究进展 无论在传热还是在传质过程中,对 Rayleigh-Bnard 对流研究可以分为实验 观测、理论分析、数值模拟。. 实验观测法在得到直接数据的 … sleep study clinic in mississauga
