| Abstract: | The majority of working media used in tests by the predecessors to study the heat transfer performance of microchannels pertain to fluids with a low viscosity and very few pertains to fluids with a high viscosity.With aviation kerosene and water serving as the working medium respectively in the test and Reynolds number in the laminar flow state ranging from 10 to 100,the heat transfer performance of two fluids in microchannels was experimentally studied.The aluminium-base microchannel array included 163 mic... |
