Abstract: | Computational modeling and simulation of irrigation systems have received the greatest attention today because of large amount of energy consumption. The use of water containing suspended sediments causes serious problems to irrigation systems. Prefilters, such as the hydrocyclone, are important for their significant capability of retaining particles suspended in the water. In this paper commercial CFD (Computational Fluid Dynamics) package called Ansys is applied to build a computational model of hydrocyclone whit two cone sections and calculate the results of separation process. The hydrocyclone has modeling whit the proper geometrical relationship between the cyclone diameter, inlet area, vortex finder, apex orifice, and sufficient length providing retention time to properly separation particles. The main parameter is the hydrocyclone diameter Dc=250 mm. Two models, i.e. Plitt’s (1976) and Lynch and Rao (1968) have been used to describe the performance of hydrocyclones, which by linking to separation device model allows for closed-circuit simulations. By comparing the outputs of ANSYS with previously existing simulators results published in the subject literature, particularly FLUENT, its performance was firmly validated both in terms of accuracy and precision of obtained results. |
