Abstract
The results of numerical simulations using the Nonlinear Disturbance Equations (NLDE) for viscous test cases in laminar flow are presented. The NLDE are implemented in a two-dimensional, finite volume code to test the algorithm's properties for viscous, wall-bounded flows. Testing focused on the accuracy of unsteady phenomena. An overview of the method, details on the implementation of boundary conditions, and results for a benchmark scattering problem and viscous flow over a circular cylinder are presented. The results show this method converges to a time accurate periodic condition using a variety of inputs for the mean flow field, and under some circumstances may converge substantially faster to the periodic state compared to the same code using a standard Navier-Stokes formulation.
