Autonomous Valve CFD (AVC) is an AI-powered virtual flow loop testing app that precisely calculates valve flow performance parameters, such as Cv, Cdt, K, σ, and FL at the design stage, using CFD simulations on the cloud. Autonomous Valve CFD (AVC) performs virtual flow loop tests that replicate the conditions of physical flow loop testing, without the associated time and cost overhead. It generates a detailed valve performance report in a couple of hours, providing critical parameters such as Valve Flow Coefficient (Cv), Coefficient of Hydrodynamic Torque (Cdt), Cavitation Index (σ), and simulation flow insights. The CFD simulations are conducted in compliance with industry standards, including ANSI/ISA–75.02.01, IEC 60534-2-3, and the M49 Manual, ensuring accuracy and reliability on par with certified laboratory tests. AVC's autonomous CFD algorithm eliminates the need for in-depth CFD expertise through automation of complex simulation processes, along with the intelligence to select the right mesh size, numerical schemes, and turbulence models appropriate for the valve under study. It offers an intuitive, user-friendly interface with guided workflows, significantly reducing the learning curve and speeding up project completion. Design engineers can simulate valve designs directly, eliminating the need for specialized CFD knowledge.
