在这项研究中，一个迭代和顺序逆传热分析程序的开发和实施到一个二维有限元程序。所开发的程序被用来确定在工业规模的试验设备的冲击水射流冷却的固定热板的驻点处的热流密度。实验数据分析表明，滞止点的传热特性主要受水温的影响，受水流量的影响较小，钢级的影响较小。所得沸腾曲线特征和典型值与文献数据吻合较好。
In this study an iterative and sequential inverse heat transfer analysis procedure is developed and implemented into a two-dimensional finite element program. The developed program is used to determine the heat fluxes at the stagnation points of stationary hot plates cooled by impingement water jets in an industry scale test facility. Analysis of data shows that the heat transfer behavior at the stagnation is mainly affected by water temperature and hardly affected by water flow rate with mild effect from steel grade. The features of boiling curves and the typical values obtained are in good agreement with data in the literature.
