Abstract	The current research deals with the experimental investigation of the heat transfer behavior and optimum relative width parameter of the multi V-down pattern perforated baffle rectangular duct. The 60° angled multi V-down perforated pattern baffle are attached on the lower duct wall having an aspect ratio (W D /H D ) of 10.0 and a Reynolds number (Re) ranging from 4000 to 9000. The experiment was conducted by varying the relative baffle width (W D /W B ) ranging from 1.0 to 6.0, relative baffle height (H B /H D ) was 0.5, relative baffle pitch (P B /H B ) was 10.0, relative hole position (O B /H B ) was 0.44, open area ratio (β O ) was 12 %. The experimental investigation shows that at a relative baffle width of 5.0 the thermal performance was maximized. Thermo-hydraulic performance (η p ) comparison shows that multi V-down pattern perforated baffle has better outcomes as compared to other baffles shaped rectangular duct.
