1. The document describes an experimental study and computational fluid dynamics (CFD) analysis of flow through a venturi meter. The venturi meter geometry was modeled in NX and meshed in ANSYS. CFD analysis was conducted using ANSYS Fluent to simulate flow and calculate pressure changes. 2. Experimental data was collected for different flow rates and used to calculate the discharge coefficient. CFD results for discharge coefficient were also calculated and found to be within 15% of experimental values. 3. The study demonstrated that CFD can be an efficient and accurate method for calibrating flow meters like the venturi meter, providing a alternative to costly experimental calibration methods.
