Flow Analysis for the Nacelle of an Advanced Ducted Propeller at High Angle-of-Attack and at Cruise with Boundary Layer Control

摘要

An axisymmetric panel code and a threedimensional Navier-Stokes code (used as an inviscid Euler code) were verified for low speed, high angle-of-attack flow conditions. A three-dimensional Navier-Stokes code (used as an inviscid code), and an axisymmetric Navier-Stokes code (used as both viscous and inviscid code) were also assessed for high mach number cruise conditions. The boundry layer calculations were made by using the results from the panel code or Euler calculation. The panel method can predict the internal surface pressure distributions very well if no shock exists.
