Abstract: The development of integrally cast turbine airfoils allows the production of narrow impingement channels in a doublewall configuration, where the coolant is practically injected within the wall of the airfoil providing ...

Abstract: The current capabilities of the foundry industry allow the production of integrally cast turbine airfoils. Impingement cooling effectiveness can be then further increased due to the manufacturing feasibility of narrow ...

Abstract: We present a macrohomogeneous two-phase model of a proton exchange membrane fuel cell (PEMFC). The model takes into account the mechanical compression of the gas diffusion layer (GDL), the two-phase flow of water, the ...
