Resolution requirements for large eddy simulation (LES), estimated by Chapman [AIAA J. 17, 1293 (1979)], are modified using accurate formulae for high Reynolds number boundary …
Turbulent flows of practical relevance are often characterized by high Reynolds numbers and solid boundaries. The need to account for flow separation seen in such flows requires …

In this work, a data-driven wall model for turbulent flows over periodic hills is developed using the feedforward neural network (FNN) and data from wall-resolved large-eddy …
Scientific research and engineering practice often require the modeling and decomposition of nonlinear systems. The dynamic mode decomposition (DMD) is a novel Koopman-based …
G Grötzbach - Nuclear engineering and design, 2013 - Elsevier
Nuclear heat transfer applications with low-Prandtl number fluids are often in the transition range between conduction and convection dominated regimes. Most flows in reactors …

The intrinsic 3D vortical structures of turbulent cavitating flow are difficult to be measured in experiment. In the present work, the compressible large eddy simulation (LES) was …
Y Cao, T Tamura, H Kawai - Computers & Fluids, 2020 - Elsevier
In the past, the coarse spanwise resolution was widely used for high-Reynolds-number flow simulations of a two-dimensional bluff body with the purpose of reducing the computational …

As energy consumption saving becomes an urgent need in the contemporary world, the demand for improving pump energy efficiency is attracting increasing attention. This paper …
The present work extends the parametric investigation on the sampling nuances of dynamic mode decomposition (DMD) under Koopman analysis. Through turbulent wakes, the study …
