Generating wall-bounded turbulent inflows at high Reynolds numbers
Ronith Stanly, Timofey Mukha, Martin Karp +2
One of the main challenges in simulating high Reynolds number () turbulent boundary layers (TBLs) is the long streamwise distance required for large-scale outer-layer structure…
Effects of lower floating-point precision on scale-resolving numerical simulations of turbulence
Martin Karp, Ronith Stanly, Timofey Mukha +11
Modern computing clusters offer specialized hardware for reduced-precision arithmetic that can speed up the time to solution significantly. This is possible due to a decrease in da…
Wall-modeled large-eddy simulation based on spectral-element discretization
Timofey Mukha, Philipp Schlatter
This article analyses the simulation methodology for wall-modeled large-eddy simulations using solvers based on the spectral-element method (SEM). To that end, algebraic wall model…
Efficient prediction of turbulent flow quantities using a Bayesian hierarchical multifidelity model
Saleh Rezaeiravesh, Timofey Mukha, Philipp Schlatter
High-fidelity scale-resolving simulations of turbulent flows quickly become prohibitively expensive, especially at high Reynolds numbers. As a remedy, we may use multifidelity mode…
An improved air entrainment model for stepped spillways
Silje Kreken Almeland, Timofey Mukha, Rickard E. Bensow
Numerical modelling of flow in stepped spillways is considered, focusing on a highly economical approach combining interface capturing with explicit modelling of air entrainment. S…
Predictive Accuracy of Wall-Modelled Large-Eddy Simulation on Unstructured Grids
Timofey Mukha, Rickard E. Bensow, Mattias Liefvendahl
The predictive accuracy of wall-modelled LES is influenced by a combination of the subgrid model, the wall model, the numerical dissipation induced primarily by the convective nume…
LES of a classical hydraulic jump: Influence of modelling parameters on the predictive accuracy
Timofey Mukha, Silje Kreken Almeland, Rickard E. Bensow
Results from large-eddy simulations of a classical hydraulic jump at inlet Froude number 2 are reported. The computations are performed using the general-purpose finite-volume base…
Flow dynamics in the closure region of an internal ship air cavity
Timofey Mukha, Rickard E. Bensow
This work is dedicated to providing a detailed account of the flow dynamics in the closure region of an internal ship air cavity. A geometrically simple multiwave test cavity is co…
Systematic Study of Accuracy of Wall-Modeled Large Eddy Simulation using Uncertainty Quantification Techniques
Saleh Rezaeiravesh, Timofey Mukha, Mattias Liefvendahl
The predictive accuracy of wall-modeled large eddy simulation is studied by systematic simulation campaigns of turbulent channel flow. The effect of wall model, grid resolution and…
