Understanding flow through the valve is essential in optimum valve design. CFD helps in predicting the valve performance and gives a good insight into the flow physics. This involves a series of CFD simulations for different valve openings (minimum to maximum) and calculates the Cv value at each condition. With the emergence of cloud computing, virtual testing of designs and performance optimization has become possible through a cloud-based CFD app, with a reduced need for producing physical prototypes.

Autonomous Valve CFD (AVC) is a cloud-based app for predicting the performance of valves using fluid flow simulations. The app provides a web browser-based graphical interface that allows designers to perform flow simulations on their valve geometry and compute valve flow coefficient curves Cv & Kv and coefficient of hydrodynamic torque Cdt.
