Direct numerical simulation of controlled transition in a flat-plate boundary layer

U Rist, H Fasel - Journal of Fluid Mechanics, 1995 - cambridge.org
The three-dimensional development of controlled transition in a flat-plate boundary layer is
investigated by direct numerical simulation (DNS) using the complete Navier-Stokes …

Investigations of time-growing instabilities in laminar separation bubbles

U Rist, U Maucher - European Journal of Mechanics-B/Fluids, 2002 - Elsevier
The occurrence of temporally growing unstable disturbances is investigated based on
eigenvalues with zero group velocity from linear stability theory (LST) and compared with …

Vortex formation and vortex breakup in a laminar separation bubble

O Marxen, M Lang, U Rist - Journal of Fluid Mechanics, 2013 - cambridge.org
The convective primary amplification of a forced two-dimensional perturbation initiates the
formation of essentially two-dimensional large-scale vortices in a laminar separation bubble. …

Mean flow deformation in a laminar separation bubble: separation and stability characteristics

O Marxen, U Rist - Journal of Fluid Mechanics, 2010 - cambridge.org
The mutual interaction of laminar–turbulent transition and mean flow evolution is studied in a
pressure-induced laminar separation bubble on a flat plate. The flat-plate boundary layer is …

Spatial resolution enhancement/smoothing of stereo–particle-image-velocimetry data using proper-orthogonal-decomposition–based and Kriging interpolation …

H Gunes, U Rist - Physics of Fluids, 2007 - pubs.aip.org
Methods for data reconstruction and spatial enhancement of experimental data for a
transitional boundary layer with laminar separation bubble are investigated. Particularly, proper …

Mechanisms for spatial steady three-dimensional disturbance growth in a non-parallel and separating boundary layer

O Marxen, M Lang, U Rist, O Levin… - Journal of Fluid …, 2009 - cambridge.org
Steady linear three-dimensional disturbances are investigated in a two-dimensional laminar
boundary layer. The boundary layer is subject to a streamwise favourable-to-adverse …

A combined experimental/numerical study of unsteady phenomena in a laminar separation bubble

O Marxen, M Lang, U Rist, S Wagner - Flow, Turbulence and Combustion, 2003 - Springer
A laminar boundary layer separates in a region of adverse pressure gradient on a flat plate
and undergoes transition. Finally the turbulent boundary layer reattaches, forming a laminar …

Electrochemical properties of laser-printed multilayer anodes for lithium-ion batteries

U Rist, V Falkowski, W Pfleging - Nanomaterials, 2023 - mdpi.com
New electrode architectures promise huge potential for improving batteries’ electrochemical
properties, such as power density, energy density, and lifetime. In this work, the use of laser-…

DNS of compressible turbulent boundary layers and assessment of data/scaling-law quality

C Wenzel, B Selent, M Kloker, U Rist - Journal of Fluid Mechanics, 2018 - cambridge.org
A direct-numerical-simulation study of spatially evolving compressible zero-pressure-gradient
turbulent boundary layers is presented for a fine-meshed range of Mach numbers from 0.3 …

[PDF][PDF] Direct numerical simulation of some fundamental problems related to transition in laminar separation bubbles

U Rist, U Maucher, S Wagner - Computational Fluid Dynamics, 1996 - Citeseer
Direct Numerical Simulations of laminar separation bubbles are presented. The bubbles are
generated by prescribing a locally decelerated free-stream velocity along a flat-plate. …
