【摘要】 热毛细对流随着近年来空间材料科学和微重力流体力学的发展引起广泛的关注.通过建立界面有相变时二维热毛细对流的数学模型,用MATLAB编程进行二维数值模拟,得到液体区温度和速度与有关无量纲参数(Ra,Ma,Pr,Bi)的内在关系,绘出了等温线分布和流函数图,证明了表面有相变对热毛细对流的影响-促进计算区域内流体的流动与传热.更多还原

【Abstract】 Termocapillary convection has been paid more attention with the progress of space material science and micro-gravity hydrodynamics in recent years. After building up the two dimensional math model of the thermocapillary convection when there is phase change at the interface, this paper simulate the result through programming using MATLAB, and get the internal relationship among the non-dimensional parameters such as Ra,Ma,Pr,Bi with the velocity and temperature in the liquid area. The isotherm distribution and stream function testify that phase change can influence the thercapillary convection, that is, promoting the flow and heat transfer of the liquid.更多还原
