Airflow in air ducts is advection dominant flow where the Reynolds numbers are between 10^4 and 10^6. Flow and pressure fields around wings of dampers in air ducts are obtained numerically at high Reynolds numbers by using Petrov-Galerkin FEM and Multi-pass Algorithm for the unsteady incompressible Navier-Stokes equations. Numerical results of pressure coefficients show good agreements with experimental data for parallel-wing dampers.
