Assessment of different turbulence models in simulating axisymmetric flow in suddenly expanded nozzles

A numerical simulation was carried out to compare various turbulence models simulating axisymmetric nozzle flow past suddenly ex-panded ducts. The simulations were done for L/D = 10. The convergent-divergent nozzle has been modeled and simulated using the turbu-lence models: The Standard k-ε model,...
