This paper presents a method based on the Computational Fluid Dynamics (CFD) for modelling the turbulent and thermal properties of the flow for cooling of a high-speed electrical machine. The method estimates the coefficients of thermal convection on the cooling surfaces of the machine, as well as the temperature and velocity fields of the coolant. The local values of the coefficients of convection are estimated for all of the cooling surfaces of the machine, including separate determinations for their inlet and outlet parts.
