碩士 / 國立成功大學 / 機械工程學系碩博士班 / 96 / The study applies the Laplace transform method and the finite-difference method in conjunction with the least-squares scheme, the square spline and temperature measurements to estimate the heat transfer coefficient on the cylindrical surface at different inclined angle. The study assumed the heat transfer coefficient on this cylinder is non-uniform. Thus the whole cylinder is divided into several sub-intervals. Later, a series of continuous square polynomial function in space and a linear function in time are introduced to estimate the distribution of the unknown cylindrical surface condition.
The results of experiment show that average heat transfer coefficient on cylindrical surface decreases with inclined angle in natural convection. A comparison of the average heat transfer coefficient between the present estimates and previous results is made in order to evidence the dependability and accuracy of the present inverse scheme.
