Numerical Study of Immersion Nozzle Outlet Flow Pattern with Swirling Flow in Continuous Casting.

Numerical Investigation of Supersonic Nozzle Flow Separation

S EPARATION of supersonic flow in a convergent–divergent nozzle is a fundamental fluid phenomenon that affects a large variety of applications, from fuel systems to aircraft engine nozzles. When a supersonic nozzle is operated at pressure ratioswell below its design point, a shock forms inside the nozzle andflowdownstreamof the shock separates from the nozzle walls. Even though flow separation ...

Numerical Study of Steady Turbulent Flow through Bifurcated Nozzles in Continuous Casting

Bifurcated nozzles are used in continuous casting of molten steel, where they influence the quality of the cast steel slabs. The present study performs two-dimensional (2-D) and three-dimensional (3D) simulations of steady turbulent (K-e) flow in bifurcated nozzles, using a finite-element (FIDAP) model, which has been verified previously with water model experiments. The effects of nozzle desig...

Melt Flow Characterization in Continuous Casting Tundishes

Melt flow in continuous casting tundishes is normal[y characterized by a combined model. The model is used to analyze the residence time disttibution of fluid in a tundish, In this model, the fluid volume in tundish is considered to be consisting of the plug flow, well-mixed flow, and dead volumes. Although this model was proposed over 20 years ago, most researchers have either used it incorrec...

Numerical Simulation of a Confined Swirling Flow in a Model Gas Turbine Combustor

numerical simulation of air-water flow in bottom outlet

flow regime in dam's bottom outlet is divided in pressurized flow and free surface flow by the gate located for discharge control. down stream tunnel involves high velocity multi component air –water flow studied by mathematical model. in this research work, we used finite volume mixture two phase flow model. because of high reynolds number, standard two equations k-e turbulence model was ...
