摘要:

针对不同结构参数的弓形折流板换热器壳程进行数值模拟,计算表明折流板换热器壳程的压降和管表面换热系数随着折流板数目的增加而增加,随着折流板缺口高度的增加而减小;而其综合性能随着折流板数目的增加而减小,随着折流板缺口高度的增加而增加;第一块折流板与管板的距离对压降的影响较小,但对表面换热系数影响相对较大.

Abstract:

Numerical simulation of the shell range of bow baffle heat exchanger with different structural parameters shows that the pressure drop and tube surface heat transfer coefficient of the baffle heat exchanger shell range increase with the increase of the number of baffles, and decrease with the increase of the notch height of the baffle. Its comprehensive performance decreases with the increase of the number of baffles, and increases with the increase of the notch height of the baffle. The distance between the first baffle plate and the tube sheet has little effect on the pressure drop, but relatively large on the surface heat transfer coefficient.
