, Eulerian-Eulerian two-fluid model, and multi-reference flame method. The mixing process in the tank was calculated by tracer method. The results show that increasing the rotating speed or gas flow...-phase flow; Eulerian-Eulerian two-fluid model; multiple reference frame method 1 Introduction With the continuous development of the zinc smelting industry and the continuous increase in the demand......
ratio both increase, but the former will decrease with the increase of work pressure. Key words: furnace; evaporation cooling; subcooled flow boiling; support tube; two-fluid model 1 Introduction... and PODOWSKI [5] established the wall heat flux partition model (RPI model) and two fluid models for numerically analyzing boiling heat transfer. These models were then modified by ISHIMOTO and KAMIJO [6......
: Based on Fluent software, the solid-liquid two-phase flow field of mechanical stirred zinc leach tank was simulated with standard k-ε turbulence model, Eulerian-Eulerian multiphase model and multi... from bottom can decrease the solid deposition at the bottom and increase the mean residence time of fluid. The appropriate distance is 0.3D. Key words: leach tank; Eulerian-Eulerian multiphase model......
