This work deals with the experimental investigation on heat transfer, friction factor, and thermal hydraulic performance of V-pattern dimpled obstacles in an air passage. The experiments were conducted in a turbulent flow regime with Reynolds number dRe_ranging from 5,000 to 17,000 using air as the working fluid under uniform wall heat flux boundary condition. The experimental investigation encompassed the geometrical parameter, namely relative dimpled obstacles widthdWc= Wd_varying from 1: 0 to 6: 0, ratio of dimpled depth to print diameter (ed= dd) from 0.50 to 2.0, relative dimpled pitch (Pb= ed) from 8.0 to11.0, relative dimpled heightded= Dh_of 0.037, and the angle of attack (aa) varying from 35 to 75 . The experimental results revealed that both heat transfer and friction factor of the air passage fitted with the V-pattern dimpled obstacles were significantly higher than those of the smooth-surface air passage. The optimum data of thermal and hydraulic performance were obtained at Wc= Wd 5: 0, ed= dd 1.0, Pb= ed = 9.0, ed= Dh= 0.037, and aa= 55. The current study shows that the thermal hydraulic performance of multi-type V-pattern dimpled obstacles shape is around 7% higher as compared to other obstacles shapes air passage.
