混合流体对流中扰动的成长

摘要

By using the numerical simulations of the two-dimensional full perturbation equations of hydrodynamics, the growth of perturbation in Rayleigh-Benard convection in the binary fluid mixture was studied. It is found that the growth rate of perturbation in linear stage is function of relative Rayleigh number r. The transition from linear stage to nonlinear regime has three types of patterns.%通过流体力学扰动方程组的二维数值模拟,研究了混合流体Rayleigh-Benard对流运动中扰动的成长.发现扰动的线性阶段成长率是相对瑞利数r的函数.从线性阶段到非线性阶段的过渡存在三种斑图结构.
