f 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 = 3Dj, 4Dj and 5Dj) and distances between jets and the dimpled surface (H = 3Dj, 4Dj and 5Dj). Additionally, dimple designs w...
