Abstract

The purpose of this work is to compare the hydrodynamic data of the real flow simulated by SolidWorks Flow Simulation in an emulsor of vortex type. The object of the study is an emulsion, in the central part of the energy separation chamber of which a zone of low pressure, the cavitation zone, is created. In this zone the dispersion phase collapses. Computer simulation of fluid dynamics of the emulsification process has been suggested to optimise the design of this type of emulsor. To check adequacy of results of modelling and real process, visualization and comparative evaluation of shape of flows at pressure of liquid at the inlet 0.4 MPa and its kinematic viscosity 10⁻⁶ m²/s. The use of SolidWorks Flow Simulation software has been found to give a fairly close-to-reality overall flow pattern. When considering the calculated flow from the position of fluid displacement and comparing it with experimental data, a good match is seen in the shape of near-axis flows. Three vortex zones are clearly visible in the model. In the real flow there are similar vortex zones which, although not clearly visible, are visualised by photography. With the software, the overall flow pattern is fairly close to reality. However, it is not possible to conclude that the velocities of the calculated and real flows coincide. By considering the various design changes in the simulation and evaluating their effect on the hydro and thermodynamics of the process, some regularities can be identified and used in the design of new designs, i.e., the results of computer simulation can be a good guide in the design of new devices.
