WHAT IS FLOWNEX®? • Software designed to assist with the development of simulation environments that require a fast, reliable and accurate total system and subsystem approach to simulation. • Simulations can be created to take into account dynamic simulations, thermal inertia, plant scenarios such as accidents and plant shutdowns, branching of flows as well as buoyancy driven flows. (Conservation of Mass, Momentum & Energy)

BENEFITS OF FLOWNEX® • Enables engineers to predict, design and optimize for flow rates, pressures, temperatures and heat transfer rates in fluid systems. • Simulations with any combination of liquid, gas, two phase, slurry and mixture flows in both steady state and dynamic cases.

FLOWNEX® SE LIBRARIES Flownex® contains a large and extendable library of components to allow users to quickly setup and model flow systems. FLOWNEX®
