Abstract

In this paper, taking transonic flow of DLR-F6 wing-body, wing-body-pylon-nacelle configurations as typical computational examples, the application of multi-block wake integration technique to complex configuration was studied. "Diagonal estimation" method was proposed to improve search efficiency of wake interpolation area and a wake interpolation method with high precision was introduced to provide an accurate aerodynamic computing platform. The numerical simulation results show that multi-block wake integration technique adopted in this paper can be used to compute aerodynamics for complex configurations with high efficiency and precision.

Key words： multi-block grid; wake integration; Navier-Stokes equation; wake interpolation
