Smart Valves

In order to support the advanced autonomy programs of the US Navy, predictive and adaptive shipboard machinery systems are generaly used. The objective in this effort has been to enable real time predictive capability to help achieve a much higher degree of autonomy than has been achieved so far. Advanced automation clearly lead to reduced manning and increased ship capability, ship survivability, and enhance the mission effectiveness, and is hence an important objective for the US Navy. In this project the actuator-valve systems as a critical part of the automation system are analyzed. Using physics-based high fidelity modeling, this research provides a set of tools to help understand, predict, optimize, and control the real performance of these complex systems.

Mathematical modeling and analysis: We derive with high fidelity the mathematical model for the behavior analysis of butterfly valves driven by solenoid actuators using multiphysics models. Based on that model, the dynamics of the valve was analyzed. The results have shown some nonlinearities responses to be considered in order to uncover harmful phenomena captured in the practice.
