Abstract

 Emitter is the key component in drip irrigation system. Therefore, hydraulic performance of emitters has an important impact on the performance and uniformity of trickle irrigation. On the other hand, process production of emitter is time-consuming and expensive. Because of small size and complex structure of labyrinth-channel used in most drip emitters, it is not possible to observe the flow behavior of water passing through the channel. In this study three types emitter (A, B and C) were selected and structural parameters of emitter channel was determined by taking photos using Scanning Electronic Microscope (SEM). Flow behavior of water in channel simulated by two COMPUTATIONAL FLUID DYNAMICS (CFD) software FLUENT and FLOW3D. Then relationship between pressure and rate of emitters discharge was calculated. Verification of the results obtained from the CFD simulation was conducted in laboratory. Average of prediction error percentage (Er) was 5.5 and 3.6 percentage for FLOW3D and FLUENT software respectively. Therefore results indicate that the FLOW3D and FLUENT softwares are a powerful technique to simulate flow behavior of the water passing through channels emitters, as well as to optimize the design of the labyrinth channel.
