Virtual zone Navier-Stokes computations for oscillating control surfaces

Research output: Contribution to journalArticlepeer-review


A new zoning method called 'virtual zones' has been developed for applications to an unsteady finite difference Navier-Stokes code. The virtual zoning method simplifies the zoning and gridding of complex configurations for use with patched multi-zone flow codes. An existing interpolation method has been modified to bring the run time for the interpolation procedure down to the same level as for the flow solver. Unsteady Navier-Stokes computations have been performed for transonic flow over a clipped delta wing with an oscillating control surface. The computed unsteady pressure and response characteristics of the control surface motion compare well with experimental data.
