... been proposed for the absorbing plate of SAHs. The Nusselt number, pressure loss pumping power, and friction factor were computed by experimental and numerical studies for three different arrangements of jets, i.e., 1 × 1 square, 2 × 2, and 3 × 3 jet array with three target plates, i.e., smooth...

.... The correlation for the Nusselt number and friction factor is formulated, agreeing with experimental data within ±12% and ±8% deviation, respectively. 1 Corresponding author. Email: 518me1007@nitrkl.ac.in Email: senapatijr@nitrkl.ac.in Contributed by the Solar Energy Division of ASME...

... closure. A detailed analysis of the Nusselt number, temperature distribution over the SAH, and friction factor across the SAH duct is done. Empirical correlations for the estimation of heat transfer and friction factor have been developed as functions of the base angle of the duct and Reynolds number...

... to 12,000, relative roughness pitch (p/e) ranging from 8 to 12, relative roughness height (e/d) of 0.0433, and the angle of attack (α/90) of 0.3333. The investigation has covered different performance parameters such as Nusselt number, friction factor, and thermal performance factor of rough and smooth...

... and longitudinal pitch ratio on Nusselt number and friction factor have been discussed. It is seen from the analysis that there is a significant improvement in Nusselt number for the case of helicoidal fin of wire diameter ratio of 1 when compared to base model as well as straight fin model for the operating range...
