Webinar – Use Reduced Order Models to Optimize Performance of Fluid Systems

In this webinar we will demonstrate how Reduced Order Modelling in Ansys Twin Builder is used to combine detailed three-dimensional Computational Fluid Dynamics representations of individual components with one-dimensional representations of large fluid systems in Flownex.


To design efficient and reliable fluid systems within increasing cost and tighter time constraints requires a detailed understanding of the interactions of complex components, like heat exchangers, with the broader system. Without this understanding, components risk being overdesigned to satisfy their broad interface constraints, may operate incorrectly where selected constraints do not reflect true system conditions, or may introduce unexpected emergent behaviours into the system as a whole which might prove costly once under operation.

In this webinar we will demonstrate how Reduced Order Modelling in Ansys Twin Builder is used to combine detailed three-dimensional Computational Fluid Dynamics representations of individual components with one-dimensional representations of large fluid systems in Flownex. The example also illustrates how the Functional Mockup Interface standard enables sharing of models between disciplines, teams and organisations in a digital world.

Flownex Simulation Environment is a one-dimensional engineering tool for the simulation of flow and heat transfer plant components as a complete integrated system with control. Components include fundamental physics which means the system behaves dynamically as close to the real world plant as possible. This allows engineers to do virtual prototyping and analysis.

Ansys Twin Builder is a powerful platform for modelling, simulating and analysing virtual systems prototypes and creating simulation-based digital twins. It includes advanced Reduced Order Modelling tools to integrate 3D physics into system simulations. This allows product development teams to verify and optimize performance of their software-controlled, multi-domain systems designs and deploy them as digital twins.

About the Speakers:


Edward Carman – Senior Application Engineer – Ansys. Edward started his career in heavy industry, designing and building ferrochrome smelters in his native South Africa, before moving into the more numerical world of pure simulation. After many years of commercial structural simulation, as well low frequency electromagnetics and fluid dynamics simulation, he decided that a shift in focus was in order and his current focus is now on system modelling and reduced order models to enable digital twin workflows.


Vincent Britz – Simulation Specialist, Solver Developer – Flownex. Vincent has dedicated his career to becoming an expert in thermodynamics and fluid mechanics. His education focused on applying the fundamentals of thermo-fluids phenomena to solving practical real-world problems in fuels and power generation research. Vincent has since been working at the head office of Flownex where he plays a key role in developing the fundamental theory required to advance the Flownex SE software. He is also very involved in many industries such as sCO2, HVAC and turbomachinery where he assists clients in getting the most from their simulations through high level technical support and consulting projects.
