Abstract

The current study numerically analyzes the heat transfer enhancement and laminar fluid flow characteristics of four flat tubes with varying attack front airflow. The heat transfer characteristics of flat tubes are investigated in terms of Reynolds number, heat fluxes, and inclination angle. Four Reynolds numbers are studied (100, 200, 300, and 400), and three heat fluxes on the surface of the tubes are (1000, 2500, 3800 W/m2 ), the inclination angle of the four flat tubes are (30o , 45o , 90o). ANSYS Fluent software v.18 discretizes and solves the governing equations using the finite volume approach across a specified control volume. According to the available data, using flat tubes increases the heat transfer in the channel. When tubes were used, the reattachment distance was reduced. When the Reynolds number is changed from 100 to 300, the heat transfer enhancement rises from 40.8 % to 55.79 % for the increase in the heat flux of 24.99 %.
