Thermo-hydraulic performance enhancement of solar air heater with double-delta (Δ) triangular finned absorber plate: Experimental investigation and response optimization approach using RSM and Rao algorithm
Experimental investigation enhances thermo-hydraulic performance of solar air heaters, suggesting effective renewable energy solutions.
Key Points
This research aims to enhance the thermo-hydraulic performance of solar air heaters using a novel design with triangular fins.
Experimental setup developed for measuring performance at specific coordinates (28.8186°N, 78.6425°E).
Optimization using Rao algorithm and Response Surface Methodology (RSM) with three input variables: solar flux, Reynolds number, and fin base to height ratio.
Responses evaluated included outlet temperature, friction factor, Nusselt number, thermal efficiency, exergy efficiency, and thermal performance factor.
Optimum conditions identified: solar intensity of 860.606 W/m², Reynolds number of 5272.73, and fin base to height ratio of 0.8879.
