In order to accurately regulate the cabin pressure in aircraft,the outflow valve flux characteristics should be analyzed firstly. By using CFD software,the 2D simulations were carried out for pressure field and the velocity field of the valve. The fluxes in different flight altitudes and different valve angles are obtained,and the flux characteristic curves are plotted out.
