| Abstract: | Using deionized water as the working fluid,subcooled flow boiling on ZnO micro-wire surface in a vertical narrow rectangular microchannel with cross-section of 0.5 mm×5 mm is studied.The flow boiling process is observed with a high-speed camera.The mass fluxes range from 200 to 400 kg·m-2·s-1,the subcooled degree is 10 K,and the heat fluxes is up to 200 kW·m-2.The characteristics of boiling curves,average heat transfer coefficients,local heat transfer coefficients and flow patterns of subcooled flow boiling under various working conditions are analyzed. |
| Keywords: | micro-wire rectangular channel subcooled flow boiling |
