摘　　要：在前文［１］实验研究的基础上，利用带液池的多孔壁微热虹吸蒸发段模型，对颗粒多孔薄层在真空状态下的沸腾两相流与传热进行了分析，综合实验数据，建立了传热关联式。Based on the previous work[1], the effects of system vacuity on the boiling two-phaseflow and heat transfer from porous micro-structures are further revealed. With the helpof the evaporator model of porous-wall micro thermosyphon with a liquid reservoir,the corresponding boiling two-phase flow and heat transfer process are analysed. By synthesizingexperimental data, a semiempirical equation is established for predicting the boiling heattransfer performance of the particle porous layer in a vacuum state.
