The influence of guide vane on the performance of an axial fan for air-assisted sprayer

Abstract

For the axial fan used in air-assisted sprayer, it always requires a good outlet flow field. In addition to ensuring that the outlet flow field has sufficient dynamic pressure, it is also necessary to ensure that the outlet flow direction is close to the axial direction. In this paper, the influence of the profile load distribution and the solidity of the outlet guide vane on outlet flow field was studied with numerical simulation. The results indicates that increasing the solidity or using the fore-load distribution profile can effectively reduce the outlet flow angle, and result in increasing the spraying distance of the water droplet. This result can provide reference for the design of the guide vane for axial fan used in air-assisted sprayer.
