PROBLEM TO BE SOLVED: To provide a program and a device for determining the local heat transfer coefficient in a short time even when the cooling condition is changed.;SOLUTION: When the reference cooling condition is set, a stationary heat flow analysis unit 13 in a local heat transfer coefficient determination device 1 calculates the temperature distribution in a calculation area by a numerical analysis method. A reference local heat transfer coefficient calculation unit 14 obtains the reference local heat transfer coefficient href(x) based on the calculated temperature distribution. When an objective cooling condition different from the reference cooling condition is set, an objective local heat transfer coefficient determination unit 15 determines h(x) so that the reference mean heat transfer coefficient hmref to be determined by the reference cooling condition, the objective means heat transfer coefficient hm to be determined by the objective cooling condition, the reference local heat transfer coefficient href(x), and the objective local heat transfer coefficient h(x) at the predetermined surface position (x) in the objective cooling condition satisfy formula (1) h(x)/hm=href(x)/hmref.;COPYRIGHT: (C)2008,JPO&INPIT
