A finite difference method based on differential-integral equation is presented for the solution of Navier-Stokes equations for incompressible viscous flow.
The 3d viscous code had been developed to calculate flow field in rotor with tip clearance by solving three-dimensional Navier-Stokesequation with time-marching method.
In the aerodynamics domain, the time-dependant aerodynamic force on the surface of the airfoil is computed by solving the unsteady Reynolds averaged Navier-Stokesequation.
