Abstract: A new kind of self-stirring tubular reactor was presented and numerical simulation approach was adopted to investigate the flow characteristics in the novel self-stirring leaching reactor. With the same agitation speed, the influence of inlet flow rate on fluid flow in the reactor was studied. The results show that, in different inlet flow conditions, the flow velocity distribution was uniform in the axial direction, but the velocities of fluids in inlet and outlet regions were higher due to the disturbance action, and the velocity in the outlet region was lower than that in the inlet region. In the radial direction, the velocity near the wall was higher and that close to the agitating shaft was lower, which shows that the impeller blade tip made a greater effect on fluid. The circulation flow in the reactor with stirring forms more easily under the flow rate of 8.3m/s.
