Research, development and embodiment of multifunctional vortex apparatus

Abstract

Despite the great number of publications related to the research and development of technological equipment with active hydrodynamic modes, little attention was paid to multifunctional vortex devices with cross-swirling flows (VDCRFC) with a cylindrical working box, having controlled active hydrodynamics and mode-design features, which enable to expand their functionality and apply them in many technological processes. The article analyzes possible hydrodynamic conditions and characteristics of the embodiment of VDCRFC for the separation of solids, based on a mathematical model of hydrodynamics proceeding from the angular momentum conservation law, allowing with a sufficient accuracy to calculate and predict the main mode-design parameters and characteristics of the device at the design stage. The article presents the results of theoretical and experimental studies, enabling to choose the most effective hydrodynamics and to embody constructively the vortex apparatus for specific processes, taking into account the specific characteristics of the latter. The examples of alternatives of the embodiment of the vortex devices are given, depending on the functionality and features of the operating conditions
