... 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...
