Physical and Mathematical Modeling of Argon Flow and Distribution Around a Ladle Shroud-Collector Nozzle (LS-CN) Assembly

Injection and distribution of argon in a ladle shroud-collector plate nozzle (LS-CN) assembly have been investigated for three different gas delivery designs popularly used the industry to these ends, physical mathematical modeling has carried out. It is shown that flow around isolated perfect LS-CN can be effectively studied through water modeling, by introducing water, lieu argon, corresponding submerged set-up, maintaining equivalence Reynolds number at inlet ports. Accordingly, were mapped via experiments towards these, video recording as well electrical conductivity measurement techniques applied. Results thus obtained indicate circumferential assembly, designs, substantially largely non-uniform. Parallel such, steady state, two-component, homogeneous, turbulent model developed assemblies predicted numerically, embodying ANSYSTM, version 18.0. Mathematical predictions agree reasonably with observations, confirm inhomogeneous systems. In addition progressive heating transit, following injection, computationally it trends results derived from isothermal non-isothermal simulations are very similar. Finally, role natural aspiration on within range conditions investigated, assemblies, having not affected suction/aspiration phenomena.
