摘 要：<正>Flow structure and heat transfer characteristics of an axisymmetric circular jet impinging on a hot 1Cr18Ni9Ti medium plate have been simulated numerically using computational fluid dynamic (CFD) code. The relation between flow field of jet impingement and its heat transfer capability is analyzed, and the phenomenon that heat transfer at stagnation point is smaller than that of points directly around is discussed. The simulation result provides boundary conditions for thermal analysis of medium plate quenching.
