建立了零重力条件下高普朗特数液桥温度场的数值模型,并进行了数值模拟。纳维-斯托克斯方程与交错网格上的能量守恒方程相结合。在数值计算中,我们不仅考虑了自由表面变形,还考虑了环境空气的影响。采用质量守恒水平集方法对液桥进行整体数值分析,捕获两相界面。同时给出了液桥和环境气相的温度场结果。
A numerical model has been developed to investigate temperature field of high prandtl number liquid bridge under zero-gravity condition, and numerical simulations have been carried out. The Navier-Stokes equations coupled with the energy conservation equation on a staggered grid. In numerical calculations, we considered not only the free surface deformation but also the effects of ambient air. Overall numerical analysis of liquid bridge was carried out by level set method of mass conservation to capture two phase interfaces. Simultaneously, results of temperature field in liquid bridge and ambient gas-phase were given.
