概要

A hybrid unstructured Navier-Stokes code with Spalart-Allamars one-equation turbulence model has been incorporated into a CFD-based design system of Japan Defense Agency, CASPER. For the code validation, we performed transonic flow computations around ONERA Model M5 configuration, which is a high Reynolds number transonic wind tunnel testing calibration model for the JDA 2m×2m trisonic wind tunnel in Higashi-Chitose. As the first step of the unification of CFD and EFD, the wind-tunnel testing data obtained here can be expected to be useful for improvement of CFD code reliability as well as evaluation of uncertainties arising from tunnel wall constraint, flow angularity, flow turbulence, noise and so on. On wing surface pressure distributions, forces and moment coefficients and boundary layer transition lines, the CASPER is quantitatively evaluated before implementation of higher Reynolds number CFD validation computations.
