Numerical Simulation of Nacelle Flow and Temperature Field

The finite element model of the nacelle flow was established using the non-structure grids.The flow and heat transfer control equations were solved by the SIMPLE algorithm taking the real cooling flow situation in the nacelle into consideration.The flow and temperature fields were simulated and the relationships between the flow,pressure and temperature field were analyzed. Further more,according to the problems in the existing design,plans were proposed to improve the nacelle cooling situation.The effectiveness of different plans were compared and analyzed.
