| Abstract: | It gives an introduction of Wilson's method,and of the problems arising in the course of calculation.Wilson's method is a solution to the relating equation of the convection heat tansfer coefficient in the heat exchanger tube of the shell-and-tube heat exchanger.It also puts forward another solution by applying nonlinear regression analysis.In the experiment,the nonlinear regression analysis and the modified Wilson's method are combined to solve the relating equation of the convection heat transfer coefficient in the heat exchanger tube of shell-and-tube heat exchanger.The result of analysis indicates that,in contrast to Wilson's method,this one of ours is simple,fast and reliable.It can be extended to the field of convection heat transfer calculation of an heat exchanger. |
