摘要

本工作的主要目标是利用CFD评估模拟框架来预测注入气流不均匀分布对换热器结构和热流特性的影响。采用CFD(计算流体动力学)模拟研究,确定进气流量不均匀分布或不均匀分布对换热器整体重新设计及高温水力性能的影响。研究结果表明,由倾斜30度的细长管装置组成的板翅片加热元件可以实现最高的温度传递,其传热能力比(SPHEX)球形管换热器高23.22%。

CFD Assessment of Flow Maldistribution in Plate Fin and Tube Heat Exchangers
The primary goal of this work is to use CFD assessment simulating framework is to anticipate the impact of injecting air flowing mal-distribution on heat exchanger architecture and thermal flow characteristics. Using CFD (computational fluid dynamics) simulation-studies, determine the impact of air intake flow unequal distribution or mal-distribution on the complete redesign as well as high - temperature hydraulic performing ability of HEX (heat exchangers). The findings demonstrate that a plate as well as tube fin heating element consisting of an elongated tubular setup slanted by 30 degrees can achieve the highest temperature transmission, having a heat transfer ability of 23.22 percent greater than a (SPHEX) spherical pipe heat exchanger.
