Reynolds Stress Perturbation for Epistemic Uncertainty Quantification of RANS Models Implemented in OpenFOAM

Autor: Luis F. Cremades Rey, Denis F. Hinz, Mahdi Abkar

Publikováno v: Fluids, Vol 4, Iss 2, p 113 (2019)

Reynolds-averaged Navier-Stokes (RANS) models are widely used for the simulation of engineering problems. The turbulent-viscosity hypothesis is a central assumption to achieve closures in this class of models. This assumption introduces structural or

The asymmetric swirl disturbance generator: Towards a realistic and reproducible standard

Autor: Jürgen Rose, Mario Turiso, Denis F. Hinz, Martin Straka, Christian Bombis

Publikováno v: Turiso, M, Straka, M, Rose, J, Bombis, C & Hinz, D F 2018, ' The asymmetric swirl disturbance generator : Towards a realistic and reproducible standard ', Flow Measurement and Instrumentation, vol. 60, pp. 144-154 . https://doi.org/10.1016/j.flowmeasinst.2018.02.021

Flow sensors are exposed to very disparate and usually adverse flow conditions produced by the pipe configuration at the installation location. These so-called installation effects may affect the accuracy of the flow measurement. Within performance t

Stratification in hot water pipe-flows

Autor: Christian Breitsamter, Simon Graner, Denis F. Hinz

Publikováno v: Energy Procedia. 116:324-333

In district heating and cooling networks, hot or cold fluid is transported in pipe systems over long distances. Heat loss (or gain) from the fluid-carrying pipes to the surrounding is a primary driving mechanism that can lead to various thermal dynam

Downstream relaxation of velocity profiles in pipe-flow with swirl disturbances

Autor: Denis F. Hinz, Christian Breitsamter, Simon Graner

Publikováno v: tm - Technisches Messen. 83:696-711

We study characteristic flow patterns downstream of a standardized swirl disturbance generator using laser-Doppler velocimetry (LDV). To investigate the spatial development of flow patterns, we conduct LDV measurements in cross-sections located at va

Reproducibility of Experiments With Swirling Flow: Numerical Prediction With Polynomial Chaos

Autor: Denis F. Hinz, Lasse N. Skov, Alouette van Hove

Publikováno v: Journal of Verification, Validation and Uncertainty Quantification. 3

Achieving good reproducibility in fluid flow experiments can be challenging, in particular in scenarios where the experimental boundary conditions are obscure. We use computational uncertainty quantification (UQ) to evaluate the influence of uncertai

A-priori testing of alpha regularisation models as subgrid-scale closures for large-eddy simulations

Autor: James J. Riley, Eliot Fried, Denis F. Hinz, Tae-Yeon Kim

Publikováno v: Journal of Turbulence. 14:1-20

Alpha-type regularisation models provide theoretically attractive subgrid-scale closure approximations for large-eddy simulations of turbulent flow. We adopt the a-priori testing strategy to study three different alpha regularisation models, namely t
