CPFD Software will participate in the ASME 2026 Fluids Engineering Division Summer Meeting (FEDSM), taking place July 26–29, 2026, in Bellevue, Washington. As one of the premier conferences for fluid mechanics and fluid engineering, FEDSM brings together researchers and industry professionals to present advances in computational methods, experimental techniques, and engineering applications.
As part of the technical program, Saurav Mitra, Senior Staff Engineer at CPFD Software, will present the paper “Graph Neural Network Reduced-Order Models for Multiphase CFD: Fluidized Bed and Hydraulic Fracturing Applications,” co-authored by Shashank K. Karra, Keshav Ramchandran, and James Parker.
The presentation introduces a Graph Neural Network (GNN)-based reduced-order modeling framework that accelerates high-fidelity multiphase Computational Fluid Dynamics (CFD) simulations while maintaining strong predictive accuracy. Developed using data generated with Barracuda Virtual Reactor, the approach demonstrates approximately 80–105× faster prediction of transient and time-averaged flow fields, with isolated snapshot predictions achieving speedups of up to three orders of magnitude. The methodology is demonstrated on two representative industrial applications: a fluidized bed gasifier and proppant transport in hydraulic fracturing.
This work highlights the growing role of machine learning in accelerating engineering simulation workflows and demonstrates how reduced-order models can support rapid design exploration, optimization, and future digital twin applications while leveraging the predictive capabilities of high-fidelity CFD.
About ASME Fluids Engineering Division
The Fluids Engineering Division (FED) of the American Society of Mechanical Engineers (ASME) was founded in 1926 as the Hydraulic Division of the Society. Following the advances and trends in the field, the name of the Division was changed to the Fluids Engineering Division (FED) in 1962. Nine years later, the Division launched its own journal, the Journal of Fluids Engineering, which is now considered as one of the leading journals in the subject of engineering applications of Fluid Mechanics. Every year the Division organizes several conferences, meetings, symposia and fora that enjoy high reputation worldwide.
The Fluids Engineering Division is involved in all areas of fluid mechanics, encompassing both fundamental as well as applications, to all types of devices, processes and machines involving fluid flow, including pumps, turbines, compressors, pipelines, fluidic systems, biological fluid elements and hydraulic structures. The applications include single-phase and multi-phase (gas-liquid-solid, gas-liquid, gas-solid, liquid-liquid, and liquid-solid). Computational methods and instrumentation for fluid characterization are also featured.
Today, the membership of the Division extends to most of the countries in the world and spans all the Continents. Our 2019 summer meeting AJKFluids2019 was a collaboration between ASME, JSME (Japan) and KSME (Korea) and included over 700 presentations. We invite you all to participate in FEDSM-2020 our summer meeting through presentation of original work, publication in the conference proceedings, viewing exhibits, speaking with vendors and sponsors, and networking among peers. Companies are also invited to provide sponsorship for meeting activities.
About CPFD Software
CPFD Software is advancing multiphase simulation and technology. Our flagship product, Barracuda Virtual Reactor®, is a physics-based engineering software package that simulates the three-dimensional, transient, fluid-particle hydrodynamics, heat balance, and chemical reactions in industrial fluidized bed reactors and other fluid-particle systems.
Virtual Reactor™ enables researchers and engineers working with fluid/particle processes to explore a broad range of ideas, reduce physical testing costs, and minimize development risk, all while accelerating commercialization, scale-up, and overall time to market. For clients who already operate industrial units, Virtual Reactor allows engineers to determine the root cause of underperformance, reduce the risk of changes through virtual testing, and optimize solutions, all while maximizing reliability, uptime, and regulatory compliance initiatives.
The Virtual Reactor technology can be accessed via software licensing, services, or custom collaborative arrangements.
