Numerical simulation of heat transfer in a tube bundle of a shell-and-tube heat exchanger used in transport

Abstract

Currently, the problem of heat removal and recovery in transport is relevant. Of the many existing designs of heat exchangers, about 80% are shell-and-tube heat exchangers. In this work, numerical simulation of the transverse air flow around a tube bundle with a diameter of 5 mm is carried out. The bundle is formed by pipes with a diameter of 0.1 to 0.5 mm. For each pipe diameter, a bundle model with different packing porosity was created. Porosity ranged from 0.7 to 0.95. The calculations were carried out in the ANSYS software package (v. 19.2). The influence of pipe diameter and packing porosity on the heat flow and pressure drop was analyzed.
