讨论了沸腾流动的数值模拟。从液体到蒸汽的相变，反之亦然，通常以高度不稳定的方式发生，其中相界非常复杂。因此，直接数值模拟需要准确求解各相的纳维-斯托克斯方程和能量方程，并正确纳入非稳态相边界。这种模拟是最近才出现的，其中不稳定相界的运动被跟踪足够长的时间以允许计算平均传热。在这里，我们将描述一种已成功用于模拟沸腾流动的方法，并展示使用该方法的一些研究示例。版权所有 © 2004 ASME
Numerical simulations of boiling flows are discussed. The change of phase from liquid to vapor and vice-versa usually takes place in a highly unsteady manner where the phase boundary is very convoluted. Direct numerical simulations therefore require the accurate solution of the Navier-Stokes equations and the energy equation in each phase and the correct incorporation of the unsteady phase boundary. Such simulations, where the motion of an unsteady phase boundary is followed for a sufficiently long time to allow computation of average heat transfer are very recent. Here, we will describe one method that has been used successfully to simulate boiling flows and show a few examples of studies using the method.Copyright © 2004 by ASME
