Summary
The contribution of Dasa Airbus (DA) to the EUROSHOCK project within Task 2.1 includes the extension of the DA viscous inviscid interaction transonic airfoil code to passive shock control (SC) by the incorporation of a SC law procedure for the prediction of the ventilation velocity and by the modification of the boundary conditions and of the algebraic eddy viscosity turbulence model for wall mass flow.
Using the data base of Task 3 the extended SC code has been validated with passive SC test cases of laminar- and turbulent-type supercritical airfoils under consideration of the shock boundary layer interaction with grid adaptation. The numerical results are in agreement with the experimental data concerning the wave drag reduction but also the viscous drag increase. In addition, the SC code has been applied for a parametric study of the main passive SC design parameters to support the design of the DA LVA-1A model for passive SC.
