摘要： 为了改善普通弓形折流板换热器换热性能, 提出了一种新型折流板换热器-球面弓形折流板换热
器。建立曲率半径为0. 7 5 D的球面弓形折流板换热器和普通弓形折流板换热器数值分析模型, 得到了壳程流体流
场分布情况以及壳程压力降和传热系数。结果表明, 在相同结构参数和进口流速条件下, 球面弓形折流板换热器壳
程压力降比普通弓形折流板换热器降低8%~1 1%, 壳程传热系数比普通弓形折流板换热器降低1%~5%。

Abstract: In order to improve the performance of the conventional segmental baffle heat exchanger's heat transfer, a new type of baffle heat exchanger, namely a spherical baffle heat exchanger was proposed. Numerical analysis models for the spherical baffle heat exchanger which radius of curvature was 0.75D and conventional segmental baffle heat exchanger were established and the distribution of the shell side fluid flow field and the shell side pressure drop and the coefficient of heat transfer were obtained. The results indicate that under the conditions of the same structure parameters and the inlet flow velocity, shell side pressure drops cause by the spherical baffle heat exchanger were lower by8%～11% than those caused by the conventional segmental baffle, while the shell side heat transfer coefficient was decreased by 1%～5% compared with the spherical baffles. 
