摘要最近提出的一种隐式方案，用于在液体浸渍多孔模具期间跟踪填充前沿，该方案被扩展为提供完全填充模具的时间和最后填充点的位置的“一次性”预测。通过在填充门处应用一般边界条件，结果表明，最多可以通过求解两个线性方程组（其大小由空间离散化确定）来预测填充时间和最后填充点的位置。这一结果通过数值填充实验得出结论，该实验表明，对于各种模具型腔，“一次性”解决方案与通过多时间步模拟获得的填充时间和位置预测完全一致。
SUMMARY A recently proposed implicit scheme for tracking the filling front during liquid impregnation into porous moulds is extended to provide ‘one-shot’ predictions for the time to completely fill the mould and the location of the last point to fill. With general boundary conditions applied at the filling gates, it is shown that the time to fill and the location of the last point to fill can be predicted on solving, at most, two linear systems of equations (of size determined by the spatial discretization). This result is conked by numerical filling experiments that show, for a variety of mould cavities, that ‘one-shot’ solutions agree exactly with filling time and location predictions obtained with multi-time-step simulations.
