Intelligent Light has been performing a grid convergence study and a Reynolds number study using OVERFLOW2 and FieldView.  The results of this study will be presented at the 2nd AIAA CFD High-Lift Prediction Workshop Sponsored by the Applied Aerodynamics Technical Committee.

 

1. Case 1 – Grid Convergence Study

  • Code: OVERFLOW2 version 2.2e
  • Grid: Coarse, medium, fine, extrafine mesh density overset grids as supplied by HiLiftPW-2 committee
  • Turbulence model: k-w-SST or Spalart-Almaras as coded in OVERFLOW2 verison 2.2e

2. Case 2a, 2b, 2c – Reynolds Number Study

  • Code: OVERFLOW2 verison 2.2e
  • Grid: Medium mesh density overset grids as supplied by HiLiftPW-2 committee
  • Turbulence model: k-w-SST or Spalart-Almaras as coded in OVERFLOW2 verison 2.2e

The OVERFLOW2 code from NASA was applied to the configuration. The OVERFLOW2 code numerically solves the compressible form of the Reynolds-averaged Navier-Stokes equations using implicit finite differences and overset grids. It has steady state algorithms and unsteady algorithms that are 1st or 2nd order in time. OVERFLOW2 utilizes overset Cartesian grids and curvilinear grids that define the surface of the wing, flap, slat and fuselage. To simulate laminar flow and turbulent flow, it uses algebraic or
2-equation models and also has the capability to perform Detached Eddy Simulations.
