Research on the Design of Flat Fan Nozzles

The design approach of internal structure parameters of flat fan nozzles with a lateral V-shaped cut was presented. With the proposed approach,a flat fan nozzle was designed and its spray effect accords with the demands. The relationship between internal structure parameters and the flow rate of a flat fan nozzle with a lateral V-shaped cut was analyzed. The radius of internal cylinder and the distance between the bottom of V-shaped cut and the axis of internal cylinder achieved their values on a group of curves. The curve moved upward as the flow rate increased. While the radius of internal cylinder was constant,the flow rate had a nonlinear increase as the depth of the V-shaped cut increased. While the depth of the V-shaped cut was constant,the flow rate had a nonlinear increase as the radius of internal cylinder increased.
