CFD simulation of the thermal behavior of a wind mill power generator nacelle
Краткое описание
In this work we use the Large Eddy Simulation model to predict the thermal behavior of the air inside of a wind generator nacelle, where several elements with different thermal characteristics are found. Outside air enters into the domain at high speed (40 m/s), thus making the flow turbulent. Given the complexity of the flow (forced and natural convection in the same domain) time-averaged models were not considered. A time explicit solver for all the variables except the pressure is used, and the velocity-pressure coupling is performed with a fractional step method. The significant results are the averaged temperatures on the different parts of the domain.
