Abstract

The bionic structure drip irrigation emitter (BSDE) is a new-type emitter, by which better hydraulic performances can be obtained. In the present work, twenty-five sets of orthogonal test schemes were implemented to analyze the influence of the geometric parameters of the flow channel on the hydraulic characteristics and energy dissipation efficiency of this emitter. Through numerical simulations and verification tests, the flow index and energy dissipation coefficient were obtained. According to the results, the flow index of the BSDE is 0.4757–0.5067. The energy dissipation coefficient under the pressure head of 5–15 m is 584–1701. The verification test has shown that the relative errors among measured values, simulated values and estimated values are less than 3%, which indicates that the flow index can be estimated reliably.
