| Abstract: | The conservative full potential equation and C H grid are used to compute the unsteady transonic flows around airfoils and wings.The equation is solved by time accurate approximate factorization algorithm and internal Newton iterations.A flux biasing technique is applied to generate proper forms of the artificial viscosity to capture shocks.The wake is modeled by solving the unsteady vorticity convection equation.A 2D integral boundary layer method based on the dissipation integral is used to account for viscous efforts.Calculations are presented for NLR7301 airfoil and LANN wing.All results are in agreement with experimental data. |
