本文提出了一种求解线性抛物型自由边界问题的全隐式数值方法。采用直线法对偏微分方程和边界条件进行时间离散。引入一个辅助函数来消除常微分方程自由边界问题中的耦合和积分边界条件。一旦得到分离的边界条件，不变嵌入用于数值求解自由边界问题。通过求解薄壁圆筒流化床涂层的传热方程，说明了该方法。
A fully implicit numerical method for linear parabolic free boundary problems with coupled and integral boundary conditions is described. The partial differential equation and the boundary conditions are time discretized with the method of lines. An auxiliary function is introduced to remove the coupled and integral boundary conditions from the resulting free boundary problem for ordinary differential equations. Once separated boundary conditions are obtained, invariant imbedding is used to solve the free boundary problem numerically. The method is illustrated by solving the heat transfer equations for the fluidized-bed coating of a thin-walled cylinder.
