- W2554998950 abstract "The formation of cavitation clusters and their influence on the flow structure inside high speed injector flows, discharging to a pressurized environment, is studied using a Homogeneous Equilibrium Model (HEM) type model. The model treats the liquid and vapor phases as continuum and uses an equation of state to link the phases and to obtain effective mixture properties. Two-dimensional compressible two-phase single-fluid Navier-Stokes equations are solved using pressure based methods, incorporating PISO schemes for pressure-velocity coupling. Within a computing cell the volume fraction of vapor is determined as a function of local density change, which allows the calculation of the speed of sound of the mixture. This value of the speed of sound is used to modify the compressibility term in the PISO pressure-correction equation during transient simulations. At the nozzle exit, a Navier-Stokes Characteristic Boundary Condition (NSCBC) is applied to allow acoustic waves to pass through the boundary. Application of NSCBC is equivalent to imposing a partially reflecting boundary condition, which helps in controlling the effect of downstream reflecting waves on the characteristics of the upstream cavitation and flow structure. In all simulations the nozzle inlet pressure was kept constant while the ambient pressure was changed to evaluate its influence on the cavitation characteristics. The simulations found that the internal nozzle flow portrays highly transient vapor formation and shedding cycles. For sufficiently low ambient pressure (i.e., high pressure drop along the injector), the cavitation clusters formed near the nozzle entrance, extend along the walls far downstream leading to events of super-cavitation. When the ambient pressure is increased a significant shifting between longer and shorter cavity lengths occurs, which generates strong recirculation regions within the nozzle. Mechanisms such as cavity stretching and cluster pinch-off were observed, exhibiting apparent non-periodic frequencies." @default.
