失重环境下液—气界面静平衡形状是液体推进剂管理系统设计的依据,是流体动力及热传导分析的初始条件,因此很多人在这方面提出了分析方法并进行了试验。因所求解必须满足贮箱中气体体积的初始值和由液体性质及贮箱材料所确定的液—气界面与贮箱壁接触角θ的边界条件,须解不定边值微分方程组,计算工作量较大。 The static equilibrium shape of the liquid-vapor interface under weightlessness is the basis of the design of the liquid propellant management system and is the initial condition for hydrodynamic and thermal conductivity analysis. Therefore, many people put forward analytical methods in this respect and conducted experiments. Due to the fact that the solution must satisfy the initial value of the gas volume in the tank and the boundary conditions of the contact angle θ between the liquid-vapor interface and the tank wall as determined by the properties of the liquid and the tank material, differential equations of indefinite boundary value Larger amount.
