PENGARUH KONFIGURASI SIRIP KOLEKTOR PANAS TERHADAP KINERJA TERMAL PADA LUAS PERMUKAAN PERPINDAHAN PANAS YANG SAMA MENGGUNAKAN CFD

Abstract

This study aims to analyze the effect of fin configuration on the thermal performance of a heat collector with the same heat transfer surface area using two-dimensional Computational Fluid Dynamics (CFD) simulation. Two heat collector models were tested: Model A with straight fins and Model B with inclined fins, each tested at three different air inlet velocities of 1 m/s, 1.5 m/s, and 2 m/s, with a constant inlet air temperature of 30°C. The simulation results showed that Model B (inclined fins) resulted in lower outlet temperatures compared to Model A (straight fins) at all air velocity variations. This indicates that the inclined fin configuration is more efficient in heat transfer and delivers better thermal performance. The significant reduction in outlet temperature in Model B demonstrates that the inclined fin design is more optimal for improving heat collector efficiency. This study provides important insights for the development of more efficient heat collector designs in solar energy applications.
