Abstract

The invention provides a solid particle distribution method and device for researching a liquid-solid two-phase flow in a water tunnel, and the method comprises the steps: mixing solid particles withwater, putting the mixture into a stirring barrel, and adding a surfactant at the same time to form a mixed solution; the magnetic stirring rotor rotating and adding the surfactant, so that the solidparticles are uniformly dispersed and fully wetted in water, injecting the mixed liquid into the mixed liquid distributor through the water pump and the flow guide pipe of the power device, and finally, the mixed liquid flowing into the water tunnel through the mixed liquid distributor. The device mainly comprises a power system, a water pump, a stirring barrel, a magnetic stirring rotor, a magnetic stirrer, a flow guide pipe, an electromagnetic valve, a mixed liquid distributor, a mixed liquid distribution pipe and a mixed liquid distribution box. The phenomenon that particle clusters, namelya large number of particles are aggregated into blocks, of mixed liquid is avoided, and solid particles can be quantitatively, stably and evenly distributed in a water tunnel.

Description

technical field [0001] The invention belongs to the field of experimental fluid mechanics, in particular to a solid particle distribution method and a device for studying liquid-solid two-phase flow in a water tunnel. Background technique [0002] Liquid-solid two-phase flow occupies an important position in two-phase flow. Its related theories and applications are spread in various fields of production, life and engineering technology. There are pseudo-ordered large eddy structures in turbulent flow, and these structures interact with solid particles. Such as the settlement of solid particles, the wear of solid particles on the wall surface, the friction resistance of the wall surface to the flow, the heat transfer of the wall surface, etc. In order to master and understand the movement law of liquid-solid two-phase flow, experimental research is usually carried out in water tunnels, tanks and other equipment. In order to obtain accurate experimental data, it is usually nec...
