Abstract

This research investigates the heat transfer characteristics and heat flux distribution associated with parallel jet impingement on a vertical flat plate. A comprehensive computational fluid dynamics (CFD) analysis is carried out and systematically validated against available experimental data to ensure the accuracy and reliability of the numerical model. The jet length is maintained constant at 12 mm, while the jet-to-plate separation distance is varied at 6, 12, 18, and 24 mm to study its influence on the thermal performance. The analysis emphasizes the effect of the jet-to-plate distance ratio (e), which ranges from 0 to 2, along with the Reynolds number under turbulent flow conditions. These parameters play a crucial role in determining the flow behavior, turbulence intensity, and resulting heat transfer rates at the impingement surface. Turbulence models within the CFD framework are employed to capture the complex flow structures and thermal interactions occurring near the plate surface. Furthermore, a comparative investigation is conducted using two different working fluids, carbon dioxide (CO₂) and air, to evaluate their relative heat transfer capabilities under identical operating conditions. The results indicate notable variations in heat flux distribution and local heat transfer coefficients depending on the fluid properties, jet-to-plate spacing, and Reynolds number. The comparative analysis between CFD simulations and experimental measurements demonstrates strong agreement, confirming that the numerical approach can reliably predict the thermal and flow characteristics of parallel jet impingement systems.

Keywords: Computational fluid dynamics, H/D, heat flux, Reynolds Number, vertical plate
