Numerical heat transfer in porous media heat exchangers of transport vehicles under unsteady flow
Due to the low metal consumption of heat exchangers with porous media, their use in cooling systems of transport vehicles is essential. This paper presents the results of a numerical study of heat transfer in a porous medium with a laminar pulsating airflow. The porous medium is represented as a two-dimensional channel with a row of square tubes and a porosity of 0.75. The pulsation amplitude corresponded to the values 1, 2, and 3; the pulsation frequency was 0.5, 0.75 and 1 Hz. A comparison of symmetric pulsations with asymmetric ones is made. It is shown that the intensification of heat transfer is increasing with symmetrical pulsations. Empirical correlations are given for predicting heat transfer with symmetric and asymmetric pulsations.
