| Abstract: | A method of solving the correlation of the convective heat exchange coefficients in the tubes of heat exchangers using Wilson diagram method was presented,and a solving method of using non-linear regression analysis was proposed for the existing problems of Wilson diagram method in calculation process.Through tests,a combined method was proposed for solving the correlation of the convective heat exchange coefficients in the tubes of heat exchangers using non-linear regression analysis and the corrected Wilson diagram method,and the method was compared with the typical empirical comprehensive formula.The result shows that the combined method is simple,fast,accurate,and reliable in comparison with Wilson diagram method. |
