Internal Flow Field Analysis of Air-Suction Roller-Type Precision Metering Device

Abstract:

In order to analyze the influence of structure parameter of air-suction roller-type precision metering device on the flow velocity and pressure, the flow field was calculation and simulation. Take the compressibility and the viscosity of the real gas into account, the N-S equations, RNG k-ε turbulence model and wall function were applied to measure the flow rate and pressure of the outlet under the conditions of changing the area of the suction holes and the diameter of shaft. The results revealed that compared with the shaft holes area, the diameter of center axis have a marked influence on the flow velocity and pressure of outlet. When the area of suction holes is constant, with the increase of shaft diameter, the outlet velocity increased and pressure decreased; when the diameter of axle is constant, with the shaft holes area increase, the outlet velocity increased and pressure decreased.
