Study of heat transfer in a heat exchanger with porous granules for use in transport

Abstract

Currently, the problem of heat removal in transport is relevant. The paper presents numerical simulation of air flow through a granular layer with perforated granules 5 mm in diameter with different hole diameters: 0.5; 0.75; 1; 1.25; 1.5; 1.75; 2; 2.25; 2.5; 2.75; 3; 3.25; 3.5; 4 mm. Numerical simulation was carried out in the ANSYS Fluent (v. 19.0) software package for various air flow velocities. The analysis of the effect of the diameter of the hole in the granules and air velocity on the heat flux, outlet temperature and pressure drop was carried out.
