This research employs numerical simulation to investigate the influence of dimple configurations on heat transfer. Specifically, it focuses on the 3x3 array of jets directed at a dimpled target surface. The study explores various jet pitches (P = 3D_j, 4D_j and 5D_j) and distances between jets and t...
