针对喷嘴的工作特性及结构特点，运用流体动力学方法对喷嘴内含3、4、5及6块挡流板等4种情况进行热分析，依据涡流强化传热理论，探讨喷嘴腔壁面及剖面（y=0）温度分布规律。研究表明：喷嘴内含3、5及6块挡流板装置时，横切面壁面处的强化对流给热系数和散热量相对较小；液体入口近端和远端喷孔处热分布规律大致相同。为进一步应用数值方法优化喷嘴内部结构，提高其整体性能打下了基础。

According to nozzle working characteristics and structure characteristics, this paper uses fluid dynamics method for nozzle with 3, 4, 5 and 6 block baffle flow board 4 on thermal analysis, and discusses the nozzle cavity wall and profile (y=0) temperature distribution, on the basis of the eddy current strengthening heat transfer theory. Research shows when the nozzle has 3, 5 and 6 block baffle device, there will be a lower strengthen convection heat transfer coefficient and Heat dissipating cross-section; and the spray holes ends have roughly the same thermal capacity at the wall surface of at liquid inlet proximal and distal distribution. This paper has done a previous job for the further application of numerical method optimization nozzle internal struclure and improvement of the nozzle overall performance.
