Simulation and Analysis on Flow Field in Leaching Tank With Dual-impeller for Alkali Cooking Tungsten Ore

Computational fluid dynamics method was applied to study three-dimensional flow field in leaching tank with JH type axial impeller and straight blade impeller.The velocity field,pressure field and turbulent kinetic energy field in leaching tank were analysized rotating at constant speed of 300 r/min and taking the fluid of sodium hydroxide mixed with tungsten ore as simulation object by using the multi-reference frame(MRF) and standard k-ε turbulent model.The research provided scientific basis for structure optimization design of leaching tank.
