FORT WORTH, Texas (PRWEB) August 04, 2020
Pointwise released a webinar where Chris Sideroff, Ph.D., managing director of Applied CCM Canada, uses Pointwise and the Caelus Python Library to understand the influence exerted by the turbulence model on computational fluid dynamics (CFD) simulation results for the FDA Blood Pump benchmark geometry.

CFD can be used to influence decisions early in the design process. In order to assess the state-of-the-art of CFD and its predictive capability for medical devices, the U.S. Food and Drug Administration (FDA) developed two benchmark models for validation. Previous work explored hybrid and multi-block structured meshing strategies and their impact on steady-state solution accuracy for one of the benchmark cases, a centrifugal blood pump. In this case study, the focus was to extend the previous study by examining the influence of the turbulence model. The k-ω SST, standard k-ε and realizable k-ε turbulence models were used. Results from all six pump test conditions were compared for each turbulence model.
Discover how to:
- Run a parametric analysis using Caelus and the Caelus Python Library.
- Write Caelus command line applications and usage.
- Use meshing techniques to improve volume grid quality in regions between surfaces in close proximity.
