Effect of Vortex Generator on the Air-Side Thermal-Hydraulic Performance of Flat Tube Heat Exchangers

In the current work, the thermal-hydraulic performance of fin and flat tube heat exchangers with and without the addition of vortex generators are experimentally investigated in a relatively low Reynolds number flow. For the experimental data collection, the existing wind tunnel available at the Fa...
