| 摘 要： | 基于单点测温、常热流假设,任意未来时间步长的导热反问题算法求解浸没水射流冷却过程的热流密度;采用有限容积法离散方程,附加源项法处理边界条件。表面施加三角形热流的经典算例验证了算法的正确性。水冷实验数据分析结果表明:射流能提高热流密度和临界温度,缩小过渡区温度区间。

| Abstract: | A numerical method,based on single temperature sensor,constant heat flux assumed and arbitrary number future time steps,was employed to determine the heat flux during rapid cooling on high temperature surface with multiply immersed impinging water jets.The finite volume discretization method and treatment of boundary condition were presented.Validating test case indicates the proposed method can predict the angular heat flux correctly.The experimental results show that water jet impingement(induces) higher heat flux,higher critical temperature and narrower transition temperature range. |
