abstract

Curve fitting method is often used in the test of heat transfer performance of heat exchangers. The convective heat transfer coefficient may be obtained with the method. However, there are defects with the method. A New Curve fitting method is introduced in this paper. Optimum seeking method is adopted in the New Curve fitting method. The new method is a practical method for test of convective heat transfer coefficient. There are few constraint with the method. Moreover, the results are more precise and the test is more convenient. The method is especially suitable for test of convective heat transfer coefficient of finned tubes outer surface. Two instances of use of the method are given.
