    摘要:Four volume fractions Al2O3-water nanofluids (0.5%, 1%, 1.5% and 2%) are introduced into free single jet impingement experiment as working fluids. The Reynolds numbers, impact angles and nozzle-to-plate distances (H/D) are variable for investigating the heat transfer performance. As to get observation of flow characteristics in nanofluid, heat transferring performance would be studied in this case. Experimental results show that there is a relationship between convective heat transferring coefficient and nanoparticles suspendability within base fluid. Convective heat transfer coefficient is proportional to the extent of nanoparticles concentration, Reynolds number while it decreases with the increasing angle of impacting. In addition, considering the influence of the suspended nanoparticles and the condition of impinging jet, a heat transfer correlation has been proposed combining the influence of the suspended nanoparticles and the condition of impinging jet.
