Numerical investigation of turbulent swirling flames with validation in a gas turbine model combustor
TL;DR: In this article, the authors performed numerical investigation of turbulent swirling flames in a model gas turbine combustor using the CFD code OpenFOAM and applied the Large Eddy Simulation (LES) approach based on the Smagorinsky model, whereas Unsteady Reynolds Averaged Numerical Simulations (URANS) are also applied, employing the Shear Stress Transport model as the turbulence model.

Dynamic Model of a Pressurized SOFC/Gas Turbine Hybrid Power Plant for the Development of Control Concepts
TL;DR: In this article, a nonlinear model with bulk parameters and 19 dynamic states is presented; the main assumptions and the underlying equations are given, and the results of both models are compared.

Pulsatile extracorporeal circulation during on-pump cardiac surgery enhances aortic wall shear stress.
Alexander Assmann,Ali Cemal Benim,Fethi Gül,Philipp Lux,Payam Akhyari,Udo Boeken,Franz Joos,Peter Feindt,Artur Lichtenberg +8 more
TL;DR: Evaluating the aortic blood flow and wall shear stress profiles under the influence of antegrade or retrograde perfusion with pulsatile versus non-pulsatile extracorporeal circulation finds that a pulsatile perfusion extensively enhanced the occurrence of turbulences, maximum blood flow speed and maximum wallShear stress.

Experimental and numerical investigation of isothermal flow in an idealized swirl combustor
TL;DR: In this paper, the authors used large eddy simulation (LES) and URANS (Unsteady Reynolds Averaged Navier-Stokes Equations or Reynolds averaged Numerical Simulations) to simulate turbulent swirling flows.
