correlation formulaの例文
- The experimental correlation formula of the heat transfer coefficient on the evaporation side in the umbrella - plate was obtained . the predicated heat transfer coefficient through the formula was finely accord with the experimental result , and the error was basically under 10 %
- Then the thermal visualizations of jet impingement cooling with single or double row holes inside semi - enclosed ribbed channel are measured by using infrared camera and the effects of flow and geometry parameters on convective heat coefficients are obtained . the results show that : the impingement cooling effectiveness of ribbed surface is affected greatly by the jet - to - surface spacing , and the best effectiveness is achieved under the jet - to - surface spacing equals to 1 . the correlation formulas of impingement heat transfer characteristics to the parameters are finally concluded and in good agree with the experiment data
