Summary
<p>Abstract: The objective of this study was to determine the total pressure loss and the separation</p><p>efficiency due to particle movement in hydrocyclone filters used in drip irrigation systems by</p><p>employing Computational Fluid Dynamics (CFD) method. For this purpose, eight hydrocyclone</p><p>filters which are commonly used in drip irrigation systems with 2", 2½", 3" and 4" inlet and outlet</p><p>diameters were considered. Pressure loss tests of these filters were carried out with clean water in</p><p>the Pump Experiment and Research Laboratory of the Department of Agricultural Engineering &</p><p>Technology in the Agricultural Faculty of Ege University. Solid models were drawn by considering</p><p>all dimensions of each filter used in laboratory experiments. In the models, flow analyzes were</p><p>carried out considering different boundary conditions and RNG k-? Model, Realizable k-? Model and</p><p>Reynolds Stress Model (RSM) turbulence models by using Computational Fluid Dynamics (CFD)</p><p>software ANSYS Fluent 16.2. Based on the analyzes, generally the Reynolds Stress Model (RSM)</p><p>was found to be the closest prediction model for the pressure loss values measured at different</p><p>flow rates. Simulation studies were carried out with this model for separation efficiency, and it was</p><p>concluded that the particle separation efficiency for a new designed hydrocyclone filter can be</p><p>approached with certain accuracy by simulation studies.</p><p>Key words: Filtration, pressure loss, hydrocyclone, separation efficiency, turbulence models</p>
