【Abstract】

<正>This paper presents the two-dimensional temperature distribution on sunrod pin fins and the boiling heat transfer coefficient onoutline in Sunrod tube.By applying the mathematical method of math-physical equation and finite difference method,thetemperature distribution on Sunrod pin fins and boiling heat transfer coefficient on outline in Sunrod tube have beenconfigured.At the same time,the comparisons of calculated values and test dates were made.The theoretical results agreedwith the tested values very well.From theoretical and experimental investigations,the boiling heat transfer enhancement ofSunrod tube is closely related to the layout density and diameter of the fins.The boiling heat transfer film coefficient of Sunrodtubes is about 1.23-1.75 times that of the plain tubes.
