Using single/multiple layers of highly conductive metallic wire mesh screen bonded to a plain heat transfer base surface, the two-phase heat transfer performance of a microjet impinging onto a porous coated copper surface was studied. Experiments were conducted at three different flow rates of water under atmospheric pressure. For comparison, experiments of jet impinging on a plain copper surface were also conducted. The results show that a base surface heat flux of 289W/cm2 is reached at a superheat of 7.9K and a jet Reynolds number of 5000 with a four-layer 200-mesh test article. Compared to jet impinging on a plain copper surface under similar working conditions, a 248% performance enhancement is obtained with the porous surface.
