摘　　要：Experiments on boiling heat transfer from a mechanically fabricated porous layer atatmospheric and superatmospheric pressures are conducted, the effect of system pressureare revealed. Based on boiling heat transfer analysis within microfin channel[6] and theobservation, a simplified model is proposed, and the boiling two-phase flow and heat transferis analyzed. By synthesizing experimental data, a corresponding correlation is established.Experiments on boiling heat transfer from a mechanically fabricated porous layer atatmospheric and superatmospheric pressures are conducted, the effect of system pressureare revealed.
