Numerical simulation of laminar solid-liquid two-phase flow in stirred tanks

摘要: Laminar flow of solid-liquid suspension has been rarely reported in the literature. In this article, laminar two-phase a lab-scale stirred tank is measured with digital particle image velocimetry (DPIV) and numerically simulated improved inner-outer iterative method. The simulation results show good agreement present data. range low solid volume concentration under investigation, particles have minor impact on flow, fields both phases are similar to counterpart single-phase liquid flow. comparison experiments shows reasonable agreement. These observations suggest that numerical method employed study reliable for analysis tanks. influence impeller off-bottom clearance velocities found significant: lower impeller, smaller radial axial velocities, higher concentration.
