Abstract:
To study the intake capacity in the pitching condition，this paper simulates the intake unsteady pitching flow by solving the unsteady Navier-Stokes equations coupled with the motion e— quation，in which the motion is pitching around the static trim attack angle of zero degree with the amplitude of fifteen degree．The simulation result shows that the unsteady flow changes with a periodicity and the intake capacity varies along a hysteresis loop which looks like a tie．
