High order finite element simulations for fluid dynamics validated by experimental data from the FDA benchmark nozzle model

In Blog, Health, HPC, News, Publication by prudhomm

The objective of the present work is to construct a sound mathematical, numerical and computational framework relevant to blood flow simulations and to assess it through a careful validation against experimental data. We perform simulations of a benchmark proposed by the FDA for fluid flow in an idealized medical device, under different flow regimes. The results are evaluated using metrics proposed in the literature and the findings are in very good agreement with the validation experiment.

Simulation of two-fluid flows using a finite element/level-set method in 3D. Application to two drop benchmarks

In Blood Rheology, Health, HemoTum++, News, Research by prudhomm

We present a numerical framework for the simulation of three-dimensional multi-fluid flows based on a finite element/level-set approach. The method allows a full Eulerian ” tracking ” of the interfaces between the fluids, and the properties of the interfaces can be directly taken into account as surface forces. The resolution of the fluid equations and the advection of the interface can be easily decoupled, which enables the use of efficient solving strategies. We also present a 3D benchmark of the rise of a drop in a viscous fluid. We use two different setups and compare our results to previous results obtained with other approaches to validate our method.
