Study on the Numerical Simulation of Helicopter Nacelle Ventilation Cooling System

摘要

Numerical simulations based on FLUENT soft were performed for the fluid field andrntemperature field of the helicopter nacelle. The physical and mathematical model of airflowrnand heat transfer were set up for the fuselage structure, helicopter nacelle, exhaust ejector andrnoutflow region. Non-structured grids were applied to the complex flow field for betterrncompute precision. A numerical simulation method which conduct the engineering design ofrnthe helicopter nacelle ventilation cooling system was formed.
