Abstract
Drip emitter is the heart of the Pressurized irrigation system, which is today’s problem-solving technology for water scarcity, especially in the agriculture sector. It emits water drop by drop to the root zone of the particular plant which is sufficient or required for the plant without the runoff losses and leaching problem. Crops need water in different quantities during its various growth stages; however, with all available emitter’s configuration, there is no means to increase or decrease flow. One has to replace the whole set of emitters to increase or decrease flow as the plants grow. The present work aims to develop a drip emitter that substitutes the above problem by a flow regulating drip emitter. The design is optimized and simulated using SolidWorks software, prototyped, tested and fabricated and has been validated with measured results. The quality of drip irrigation system is verified by emitter’s hydraulic performance. In the high-pressure pipeline, the water energy may dissipate after flowing through the different types of designed channel and the flow rate can be controlled to meet the water need of the crops. In this study variable flow Drip Emitters/emitters have been designed and fabricated in 3D printer. To ensure the emitter’s hydraulic performance, before the fabrication of emitter, computational fluid dynamics (CFD) was used to predict emitter’s flow rate and analyze its hydraulic performance under various water pressures.
