摘　　要：为探讨多孔介质对强化池内沸腾传热的机理,在38×3mm的容器内上,应用多相流VOF模型,耦合多孔介质流动与传热模型,通过添加用户自定义程序实现了对光滑和多孔加热壁面的池内沸腾传热过程进行数值模拟。数值模拟结果与实验结果相符合,所建立的数学模型为多孔介质的沸腾传热研究提供了依据。In order to investigate the mechanism of the porous medium for enhancing the pool boiling heat transfer in the size of 38 × 3mm on the electronic chip,the application of multiphase flow VOF model,coupled porous media flow and heat transfer model,by adding user-defined program for achieve the smooth and porous wall pool boiling heat transfer process were simulated. Numerical simulation agreed with the experimental results. Mathematical model established for boiling heat transfer in porous media research provides a basis.
