Type: article
Abstract: The article presents the results of a study of the influence of the shape of the flow body (TO) on the frequency of vortex formation in a vortex flowmeter with an external sensitive element. Numerical simulation using CFD (Computational Fluid Dynamics), implemented in the program for modeling physical phenomena using the Comsol Multiphysics finite element method (Femlab), was performed for three modifications of a cylindrical body of flow at three different flow velocities (0.11, 0.27 and 0.44 m/s) and a distance of 40 mm from the starting point equal to 0.017965 m. The obtained data on the frequency of vortex formation, depending on the flow velocity and the geometry of the flow body, make it possible to optimize the design of the vortex flowmeter to increase the accuracy of measurements. The dependence of the frequency of vortex formation on the flow velocity for all the studied currents has a similar character, but differs in magnitude. Further research will be aimed at studying the influence of additional parameters such as temperature and pressure.
