Abstract: In this paper, the pressure differential hierarchical throttle distributor is taken as the research object. First, the turbulence model of the flow field inside the water distributor is established. Then, using different nozzle assembly forms, the experiment is carried out at different flow rates to obtain the pressure and speed change curves. Then, using an offset long water nozzle hollow throttle core, the water nozzle is placed in different spatial positions, and an experimental study is carried out to obtain the pressure and speed change curves, and summarise the change rules therein. Finally, according to the experimental results, suggestions for effective evaluation and parameter optimisation are proposed. The research results can play a good guiding role in the design of large-pressure differential hierarchical throttling water distributor.

Keywords: pressure differential hierarchical throttle water distributor; flow field; experimental research; parameter optimisation.
