| Abstract: | The numerical simulation of axisymmetric gas stirred ladle systems has been considered and a mathematical model based on the dimensionless form of the turbulent Navier-Stokes equations developed. Embodying a simplified turbulence model in the calculation procedure, it is demonstrated from the first principles that non-dimensional velocity components at relatively low gas flow rates, follow identical distribution patterns at equivalent dimensionless bath depths and radii, provided values of the parameters L/R and Q/R2.5 are similar for the various gas stirred systems being considered. The theoretical analysis has been substantiated through numerical experimentations and by considering a set of five independant experimental studies on liquid velocity measurements reported in the literature. |
