| 英文摘要 | In this study, flow and convective heat transfer of multiple impingement jets of kerosene are investigated experimentally and numerically. A test panel with multiple impingement holes is used to perform experimental study with a heating facility. The overall heat transfer coefficient and pressure loss are measured for a wide Reynolds number range of impingement jets from 2020 to 14,260. For the present flow parameters range, Nusselt number of kerosene impingement jet cooling is found to vary with a function of Reynolds number of Re-0.7. The pressure loss coefficient decreases with the increase of Reynolds number with a function of Re-0.48. At the same time, Reynolds averaged numerical method with SST k-omega turbulence model is applied to simulate flow field and heat transfer of impingement jet cooling. The calculated heat transfer coefficient and pressure loss are well consistent with the experimental data. The numerical results clearly show the high-speed jets and strong vortices near the impingement plate cause high heat transfer efficiency. |
