摘要
通过二维流体力学基本方程组模拟了具有较强Soret效应(分离比ψ=-0.47)的混合流体在中等长高比(Γ=12)腔体内的Rayleigh-Benard对流运动。研究了不同瑞利数情况下腔体内出现的各种行进波状态,详细地探讨了Undulation行进波(UTW)的特性、时空结构及稳定性。
By the two-dimensional hydrodynamic equations, the Rayleigh-Benard convection in binary fluid mixtures with strong Sorer effect （ψ = -0.47 ） in an intermediate-aspect-ratio（Г = 12）cell is simulated completely. The patterns of various traveling wave with different Rayleigh numbers are studied, and the dynamics, spatio-temporal structures and the stability of the Undulation traveling wave are discussed in detail.
