【Abstract】 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.更多还原
