Abstract

Abstract

The thermal transient analysis result of the nuclear components contributes significant effect to the fatigue and fracture mechanics evaluation, and the key step of thermal analysis procedure is to apply the precise film coefficient. In this paper, the implement of applying the precise film coefficient is realized by using ANSYS user subroutine USERCV. The coding of USERCV subroutine, compiling and linking, application with example are also given in detail in this paper. Based on the comparison of the calculation, it is obvious that USERCV can reduce the conservative of fracture mechanic evaluation and fatigue analysis in a certain extent.
