【摘要】 为了了解微重力下水平温度梯度作用时环形浅液池内的热毛细对流特征,采用渐近线方法求得了环形浅液池内热毛细对流的近似解析解,得到了主流区速度场和温度场的表达式,并与数值模拟结果进行了比较,两者基本吻合．更多还原

【Abstract】 In order to understand the nature of thermocapillary convection under microgravity in a differentially heated annular pool,we obtained an approximate analytical solution of the thermocapil- lary convection in a thin annular pool by asymptotical way and expressions of velocity and temperature field in the core region.We compared the asymptotical solution with the numerical solution.It is found that there is a good agreement between them.更多还原
