Investigation of the flow properties of the micro jet sprinkler using computational fluid dynamics

Abstract

Objective: The objective of this study was to determine the flow properties of the micro jet sprinkler by using Computational Fluid Dynamics (CFD) method and also the most suitable turbulence model. Material and Methods: In the study, micro jet sprinklers with four different nozzle diameters were considered. In the first stage of the study, the flow rates of micro jet sprinklers at different pressures, and wetting diameters at nominal operating pressure (200 kPa) were measured. In the second stage, the values calculated with different turbulence models by using computational fluid dynamics analysis method were compared with the measured ones. Results: The flow rates for all nozzle diameters were estimated with a very low error value such as the highest 2.16% at 200 kPa, which is the nominal working pressure by using Reliz k-ε, Enh Wall turbulence model. In addition, the simulations of the water distribution in the sprinkler nozzle outlet and flapper area were found to be very close to experimental values. Conclusion: It was found that the flow rate values of the micro jet sprinkler can be estimated with very low error by using Reliz k-ε, Enh Wall turbulence model and the design of sprinkler nozzles can be achieved with simulations quickly and easily.
