For the first time, a validation challenge will be organized during the workshop. The main goal of this validation challenge is to evaluate the performance of OpenFOAM as a numerical simulation tool for addressing industrial problems and identify areas needing additional research and development in OpenFOAM. We invite the whole community to participate in this benchmarking case. Participants are invited to use different turbulence models, meshes, numerical methods, CFD solvers, etc.
On the validation challenge – Executive summary:
FDA’s “Critical Path” Computational Fluid Dynamics (CFD)/Blood Damage Project.
Validation of CFD modeling is essential to demonstrate the credibility of simulation results. To provide a benchmark data set for CFD validation, researchers at the U.S. Food and Drug Administration (FDA) and collaborators designed a geometrically simple centrifugal blood pump and performed experiments to characterize the hydrodynamic performance of the device. The pump consists of a centered rotor with four equally spaced blades, a housing, and an outlet diffuser. Interlaboratory experiments were conducted in three labs using a Newtonian blood analog fluid. The pressure head was characterized and particle image velocimetry (PIV) measurements of the velocity field were acquired in several different locations in the pump, both within the rotor region and the outlet diffuser. Experiments were performed at six pump conditions that span the device operating range. To facilitate CFD validation, the 3D computer aided design (CAD) files of the pump geometry, the fluid properties and inlet conditions, and all experimental measurements are publicly available at https://nciphub.org/wiki/FDA_CFD/ComputationalRoundRobin2Pump.
Publications – Technical notes
All presenters are invited to submit a technical note to a special issue of the OpenFOAM Journal called “Selected Papers from the 18th OpenFOAM Workshop”. The technical notes will be mainly related to reproducibility and data transparency. More information related to this special issue will be available later.
How to participate
Everybody is invited to participate in this validation challenge. No separate registration fee will be required for attendance. But you must be registered to attend the OpenFOAM workshop. To formalize your participation or to show your expression of interest, just send an email to email@example.com
