Institution National Aerospace Laboratory NLR Date 1984-03-12 Abstract The numerical integration of the unsteady full-potential equation in generalized coordinates in strong conservation form is described for the computation of unsteady transonic flows. A typical feature of the present algorithm is that non-linear truncation errors are minimized by time-linearizing the full-potential equation upto second order accuracy. The resulting second order hyperbolic equation is integrated numerically by the method of fractional steps. In this way a non-iterative time-marching procedure is obtained. The full-potential equation is discretized in space by fully conservative finite difference schemes employing mass-flux splitting for the capture of shocks. Numerical results are presented for unsteady transonic flow about a NACA 64A010 airfoil and an 0NERA-M6 airfoil.
