“…The increase in energy demand and its high cost are forcing researchers to introduce new developments in the existing irrigation technologies so that these systems could still be used as a viable source in the new era. Normal sprinkler irrigation is operated at a high pressure of around (≥300 KPa), causing more energy consumption [56]. The low-pressure sprinkler is a new addition to the existing technology, enabling users to operate sprinklers at <200 KPa and subsequently lowering operating costs with different management strategies [56][57][58].…”

The low-pressure sprinkler is a new addition to the existing technology, enabling users to operate sprinklers at <200 KPa and subsequently lowering operating costs with different management strategies [56][57][58]. The key principle of designing a low-pressure sprinkler is to change the internal nozzle structure to reduce the operating pressure without compromising the dispersion uniformity of water droplets.…”

The non-judicious use of water at the farm level in traditional irrigation application methods is a present-day concern across the world that can be resolved by enhancing application efficiency through the adoption of advanced irrigation techniques. Sprinkler irrigation is a method that has high application efficiency, which can be further increased when coupled with automation toward precision irrigation. The objectives of this review are to summarize the main aspects of sprinkler and precision irrigation and their development, scope, and future prospects specifically in Asian countries. In this paper, a modified methodology, inspired by PRISMA guidelines, was used to explore the available literature to summarize the existing knowledge in the field. Regarding the technological aspects of the analyzed works, it became evident that sprinkler systems are an efficient method to not only irrigate crops (with 39% water saving) but also for the application of fertilizers with higher efficiency (>35%) and water productivity (>14.1%) compared with gravity irrigation systems. Moreover, this paper highlights the prominent features of precision irrigation for maximizing agricultural productivity. The use of sprinkler irrigation with precision applications using automation with a sensor-based mechanism for field data collection, data transformation, data analysis, and operation of IoT-based automatic solenoid valves can save 20–30% more irrigation water and increase crop yield by 20–27%. An analytical understanding and knowledge of the field were used to draw conclusions that are thought-provoking for scientists, researchers, and other stakeholders.

“…In sprinkler irrigation systems, low pressures are considered to be below 200 kPa, intermediate pressures are in the range of 200–500 kPa, and high‐pressure levels are above 500 kPa (Jiang et al, 2020). Under their rated working pressure, impact sprinklers can spray water jets evenly on the ground driven by their swingarms.…”

Needle‐shaped water dispersion devices (NSWDDs) can break the jet and make the sprinkler spray evenly even under low working pressure. However, an inappropriate selection of the depth at which the NSWDD is inserted into the jet will affect the sprinkler pattern radius. To study the effect of the NSWDD insertion depth on the jet breakup, the jet structure, atomization, vorticity, static pressure and velocity distribution are studied using a combination of the lattice Boltzmann method and high‐speed photography. The results show that as the insertion depth increases, the jet structures gradually evolve from liquid films to ligaments, causing the diffusion angle of the jet to increase. Under the same operating pressure, the degree of jet atomization increases with increasing insertion depth. Meanwhile, the velocity pulsation degree on the central axis gradually increases, which will cause the jet to have a shorter air travelling distance. As the insertion depth and the radial position distance from the nozzle outlet increase, the velocity on the radial line first exhibits a symmetrical distribution, then an asymmetric one and finally a symmetric one again. The results can fill the gap in previous research on the effects of the NSWDD on jet breakup.
