Stability of Diffusive Shear Layers
Stefan S. Nixon, Philipp P. Vieweg
As one of the cornerstones of fluid mechanics, stability analyses provide essential physical insights into the growth of perturbations and eventual transition to turbulence. Howeve…
Anisotropy of emergent large-scale dynamics in forced stratified shear flows
Philipp P Vieweg, Colm-cille P Caulfield
Although stably stratified shear flows, where the base velocity shear is quasi-continuously forced externally, arise in many geophysically and environmentally relevant circumstance…
Effects of conjugate heat transfer on large-scale flow structures in convection
Matti Ettel, Philipp Patrick Vieweg, Jörg Schumacher
The constant temperature and constant heat flux thermal boundary conditions, both developing distinct flow patterns, represent limiting cases of ideally conducting and insulating p…
Turbulent mesoscale convection in the Boussinesq limit and beyond
Shadab Alam, Dmitry Krasnov, Ambrish Pandey +4
Mesoscale convection covers an intermediate scale range between small-scale turbulence and the global organization of the convection flow. It is often characterized by an order of…
Digital twin of a large-aspect-ratio Rayleigh-Bénard experiment: Role of thermal boundary conditions, measurement errors and uncertainties
Philipp Patrick Vieweg, Theo Käufer, Christian Cierpka +1
Albeit laboratory experiments and numerical simulations have proven themselves successful in enhancing our understanding of long-living large-scale flow structures in horizontally…
