Enhancement of Heat Transfer Coefficient in DPDGSAH having V Ribs with Symmetrical Numbers of Gaps in a Rectangular Duct: A Robust Design Approach
Jolly Lucas, Pooja Tiwari
Enhancement of heat transfer coefficient has been carried out through a solar air heater (DPDGSAH) having artificially roughened V-type geometry with symmetrical gaps and then optimized by use of Robust design method. A L25 orthogonal array is used to optimize the geometry factors for the maximum thermal performance of the ribbed channel. Thermal performance concept includes maximization of heat transfer coefficient and its thermal efficiency. Maximization of heat transfer coefficient is taken as the criteria of optimization. The investigation encompassed Reynolds number (Re) ranging from 4000 to 12000, relative roughness pitch (P/e) values of 412, angle of attack () range of 300900, relative gap width (g/e) values of 15, Number of gaps (Ng) values of 15, and relative roughness height (e/D) values of 0.043. Results show that Reynolds Number (Re), relative roughness pitch (P/e), angle of attack () have the greatest influences parameters on maximization of heat transfer coefficient.
