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.
