Abstract
Multi-scale turbulation features, including first turbulators () on a cooling surface (), and smaller turbulators () on the first turbulators. The first turbulators may be formed between larger turbulators (). The first turbulators may be alternating ridges () and valleys (). The smaller turbulators may be concave surface features such as dimples () and grooves (), and/or convex surface features such as bumps () and smaller ridges (). An embodiment with convex turbulators () in the valleys () and concave turbulators () on the ridges () increases the cooling surface area, reduces boundary layer separation, avoids coolant shadowing and stagnation, and reduces component mass.
