Accomplishment: The development of a new cooling mechanism for gas turbines rotors (blades and disks). Cooling mechanism that utilizes a compressed liquid (hydrostatic) pressurized in rotating ducts or pipes with particular physical boundary conditions (no fluid flow. no coriolis effects). High heat transfer capacities are originated, by a high intensity mixing (mass transfer) and a directional momentum exchange in the liquid particles. Although no surface work is done on the rotating liquid mass, inertial energy dissipation and periodic body forces work, originate these reactions in the liquid, as the physical and thermodynamic boundary conditions do no permit any other result. Phenomenological observations and experimental tests, confirm a strong dependence on the rotation velocity for the mixing and momentum exchange observed. Conservation laws and subsidiary equation applied to the liquid mass, indicate, an irreversible process with entropy generation.
