Cooling blade in earth
WebJan 20, 2024 · Advertisement. Earth's core has been cooling since the planet formed some 4.5 billion years ago, when the entire surface was covered with oceans of magma. … WebOne method for addressing this problem is film cooling, in which cool air is bled from the compressor, ducted to one or more internal chambers of the turbine blades, and discharged through one or more cooling holes to form cooling jets. As a result of the cooling jets, convective heat transfer to the surface of the turbine blade can be reduced.
