Effect of Homogeneous Condensation on the Interaction of Supersonic Moist Air Jets with Resonance Tube

The hartmann tube, can use for flow-control, is a device which generates high intensity sound through the shock wave oscillations, are created by the interaction of the supersonic jet. in this study, two-phase flow simulations are carried out to characterize the effect of non-equilibrium condensation on the unsteady flow field of the hartmann resonance tube. this present numerical work provides a new insight on the flow dynamics and acoustics of the resonance tube – including the shock nature, the tube gas heating, and the effect of non-equilibrium condensation on the flow structure. a tvd numerical method is applied to the reynolds and favre-averaged navier-stokes equations, and droplet growth equation of liquid phase production. the simulations are performed over a range of nozzle pressure ratios. the numerically simulated flow structure of under-expanded supersonic jets is compared with experimental data. moreover, the predicted frequency of end wall pressure fluctuations is compared with the experimental results.
