SOLIDWORKS FLOW SIMULATION SET UP PARAMETERS FOR SIMULATING ULTRASONIC FLOW METERS

Abstract

The article thoroughly examines the parameters for configuring the computer package SolidWorks Flow Simulation at the "Set Up a Flow Simulation Project" stage of the generalized CFD analysis procedure and their setup options. Additionally, the article provides a specific step-by-step example of selecting SolidWorks Flow Simulation parameters for modeling the measurement error of a two-path chordal ultrasonic flowmeter caused by the influence of flow structure distortion (velocity profile) - a typical task when researching this type of flowmeter. Based on the example, it is shown that the installation angle of the pipe fitting "two 90° bends in different planes" relative to the two-path ultrasonic flowmeter significantly affects the flow measurement error, especially at low flow velocities. As the velocity increases, the flow measurement error of the ultrasonic flowmeter stabilizes and almost does not change its value.
