摘要: This study aimed at enhancing the performance of an emitter by optimizing the flow channel and reducing the flow index, which improves the energy dissipation coefficient and anti‐clogging ability of a pit drip irrigation emitter (PDIE). Methodologies of a flow numerical simulation and a model experiment were used to evaluate the influence of four types of optimized structure schemes of PDIE. The results show that the low‐velocity vortex zone in the flow channel increased the energy dissipation coefficient, and decreased the flow index …
