Numerical simulation of turbulent compressible flows in a C-D nozzle with different divergence angles

Compressible gas flow inside a convergent-divergent nozzle and its exhaust plume atdifferent nozzle pressure ratios (NPR) have been numerically studied with severalturbulence models. The numerical results reveal that, the SST k–ω model give the bestresults compared with other models in time and accuracy. The effect of changes in value ofdivergence half-angle (ε ) on the nozzle performance, thru...

Numerical Simulation of Turbulent Bubbly Flows

A mathematical model for turbulent gas-liquid flows with mass transfer and chemical reactions is presented and a robust solution strategy based on nested iterations is proposed for the numerical treatment of the intricately coupled PDEs. In particular, the incompressible Navier-Stokes equations are solved by a discrete projection scheme from the family of Pressure Schur Complement methods. Nove...

Numerical Simulation of Turbulent Flows with Sheet Cavitation

A pressure-based algorithm is developed and applied to compute turbulent sheet cavitating flows. Single-fluid Navier-Stokes equations, cast in their conservative form, along with a volume fraction transport equation are employed. The flow is computed in both phases with the vapor pressure recovered inside the cavity via a mass transfer model. A pressure-velocity-density coupling scheme along wi...
