Pressure drop analysis of subsurface irrigation dripper system and its flow rate uniformity

Recently, water scarcity has become a serious social problem caused by global climate change. In agricultural usage, subsurface irrigation techniques can be an alternative method to save and improve the productivity quality of crops. The technique supplies burying hose 30 cm underground rather than placing it on ground (topsoil), effectively preventing evaporation loss at soil surface. this study, we numerically calculated pressure drop using dripper installed inside developed in Korea. pumping load domestic product was evaluated terms momentum compared with most widely used Netafim products. lower dripper, higher performance system stable supply. Using computational fluid dynamics experiments, provide meaningful evaluation system.
