dc.description.abstract—The object of this study was cooling of inverted and plain triangular profile copper surfaces at a constant heat flux of 1000 W/m2. The cooling of these triangular profile surfaces placed at the bottom of a rectangular channel was carried out using a single jet of air flow. The 3D geometry was analyzed with the steady state and k-ε turbulence models using the Ansys-Fluent software program. While all surfaces of the rectangular channel were adiabatic, a constant heat flux was applied to the triangular profile surfaces. The impingement air jet had an inlet temperature of 300 K. The Re number range in the study was 4000–10000, the interval between the jet and plate H/Dh being equal to 4, 6, 10, and 12. The results obtained were compared with experimental and numerical results in literature, which showed their compatibility. The results are presented as the average Nu number and the surface temperature variations for the profiled surfaces of both inverted and plain triangular profiles. The velocity, streamline, and temperature contour distributions of the jet flow along the channel were analyzed for both profiles for different H/Dh ratios. The average Nu number value was found to be 49.67% higher for the inverted triangular profile surfaces than that for the plain profile surfaces for Re of 4000 to 10000 and H/Dh = 10.tr
