Abstract

LES has proved to be a very powerful way to predict velocity dynamics and to resolve large and middle scale turbulent quantities of the flow. It is widely used today for flow calculations in science, engineering and industry. Authors present results of LES modelling of turbulent flows in a induction crucible furnace (ICF) and in a induction furnace with cold crucible (IFCC). Calculated velocity distributions are compared with experimental for Wood's metal (Sn=12.5%, Pb=25.0%, Bi=50% and Cd=12.5%) flow in ICF. Velocity and temperature distributions are calculated for TiAl flow in different IFCC systems. Results represent the large role of turbulent pulsations in IFCC temperature homogenisation. It is shown that LES model can be effectively used for investigation of species transport in the melt using the particle tracing method. The particle tracing was performed for different particle Stokes numbers.
