Computational Fluid Particle Dynamics Solutions

The emerging field of computational fluid particle dynamics (CFPD) is unlocking valuable insights into liquids, gases and particles for a broad range of applications. CFPD predicts the behavior of particles and fluids under various conditions, helping engineers optimize the performance of parts, structures and systems.

Southwest Research Institute (SwRI) offers CFPD modeling, simulation and evaluation services focused on fluid dynamics, particle dynamics, heat transfer and fluid-structure interaction. We specialize in coupling computational fluid dynamics (CFD) with discrete element modeling (DEM) and other methods.

Performance Evaluation

Design Optimization
Simulation offers a fast and cost-effective way of evaluating system performance. We apply target test conditions in virtual models and generate detailed plots (velocity, pressure, temperature) to assess performance before prototyping begins. Beyond providing performance evaluations, we support clients with optimizing component and system designs. Our expects run iterative simulations with varying design parameters to identify configurations for improved performance, efficiency, and durability .

CFD-DEM Coupling & CFD CAD Software

Our work is supported by a diverse set of advanced modeling tools, ensuring flexibility and accuracy across applications. Using CFD and computer-aided design (CAD) tools, the physical domain is replicated and discretized into a mesh. CFD solvers then apply the Navier-Stokes equations governing fluid motion to predict velocity, pressure, temperature and other flow characteristics.

Case Study: Sand Screen Coupon Erosion Analysis – SwRI conducted a series of CFD simulations using ANSYS Fluent’s Discrete Phase Model (DPM) to predict erosion in a sand screen coupon. The computational fluid particle dynamics study demonstrated strong qualitative agreement between the CFD-predicted and experimentally observed erosion patterns, validating the simulation approach for use in erosion risk assessment and design evaluation.
