摘要

利用CFD软件

通过对小型管壳式换热器建立数值模型

研究改变折流挡板倾斜角度(0°、5°、10°、15°、30°和45°)对换热器内部流场以及换热效果的影响规律。结果表明:在不同入口水速下(0.1、0.2、0.3、0.4、0.5 m/s)

换热器内水流温升率和总热传率受折流挡板倾斜角度变化的影响规律不同;随着折流挡板倾斜角度的逐渐增大

换热器内部压力分布逐渐均匀

换热器进、出口压降减小;折流挡板倾斜角度取5°时

可以获得较小的压降率、较大的温升率和总热传率。

Abstract

By using the CFD software

numerical model of a small scale shell-and-tube heat exchanger was established

and the influence of inclined angle(0°

5°

10°

15°

30° and 45°) of the baffle on internal flow field and heat transfer effect of the heat exchanger was studied. The results show that

the temperature rise rate and the total heat transfer rate are affected by the inclination angle of the baffle at different inlet flow velocities(0.1

0.2

0.3

0.4 and 0.5 m/s). The pressure drop decreases with the increase of the inclination angle at different inlet flow velocities. A smaller pressure drop rate

a larger temperature rise rate

and a larger total heat transfer rate could be obtained when the inclination angle is 5°.
