One-dimensional Bubbly Cavitating Flows through a Converging-diverging Nozzle
A non-barotropic continuum bubbly mixture model is used to study the one-dimensional cavitating ow through a converging-diverging nozzle. The nonlinear dynamics of the cavitation bubbles are modeled by the Rayleigh-Plesset equation. Analytical results show that the bubble/bubble interaction through the hydrodynamics of the surrounding liquid has important e ects on this con ned ow eld. One clea...

متن کاملTransition to chaos in converging-diverging channel flows: Ruelle-Takens-Newhouse scenario
Direct numerical simulations of the transition process from laminar to chaotic flow in convergingdiverging channels are presented. The chaotic flow regime is reached after a sequence of successive supercritical Hopf bifurcations to periodic, quasiperiodic, and chaotic self-sustained flow regimes. The numerical experiments reveal three distinct bifurcations as the Reynolds number is increased, e...
متن کاملStudy on the Variation Effects of Diverging Angleon Characteristics of Flow in Converging and Diverging Ducts by Numerical Method
The present paper develops and validates a numerical procedure for the calculation of turbulent combustive flow in converging and diverging ducts and through simulation of the heat transfer processes, the amount of production and spread of Nox pollutant has been measured. A marching integration solution procedure employing the TDMA is used to solve the discretized equations. The turbulence mode...
متن کاملPressure-driven transport of particles through a converging-diverging microchannel.
Pressure-driven transport of particles through a symmetric converging-diverging microchannel is studied by solving a coupled nonlinear system, which is composed of the Navier-Stokes and continuity equations using the arbitrary Lagrangian-Eulerian finite-element technique. The predicted particle translation is in good agreement with existing experimental observations. The effects of pressure gra...
