Abstract Flow properties were measured in the liquid-solid jet loop reactor.The liquid average velocity and the turbulent violence were measured through the modified Pito tube.The local solid hold-up was measured by using PV4A particle content equipment.It showed that the liquid average velocity,the turbulent violence and the solid hold-up increased with the increase of jet liquid flow rates. Inside the draft tube,the liquid average velocity indicated approximately the distribution of tube flow,while within the annular region,the liquid velocity distribution was uniform.The radical distribution of the solid hold-up was uniform within both the draft tube and the annular region.This flow property is fundamental to the scale-up design and optimization of jet loop reactors.
