The need to properly compute steady and unsteady viscous flows surrounding airfoils at transonic speeds an outstanding problem in fluid dynamics. In transonic flow where viscous effects such as shock-boundary interactions and separation are dominant, methods based on the Navier-Stokes equations are needed. Calculations of unsteady transonic flow about oscillating airfoils where flutter, dynamic stall, buffet, and moving shock waves on these surfaces change the entire flow fields and aerodynamic characteristics, are still stiff problems that stimulate more work and studies to be done. To simulate these problems correctly a robust computer program is needed. This report shows the works have been done up to now i.e., developing a computer program and verifying it by applying to steady viscous and inviscid flow calculations and inviscid flow about an oscillating airfoil.
