Adjoint-based aerodynamic shape optimization including transition to turbulence effects
Aerospace Science and Technology, 2020 The inclusion of transition to turbulence effects in aerodynamic shape optimization makes it possible to use it as a tool for the design of airframes with laminar flow.

Shock-induced heating and transition to turbulence in a hypersonic boundary layer [PDF]
Journal of Fluid Mechanics, 2020 The interaction between an incident shock wave and a Mach-6 undisturbed hypersonic laminar boundary layer over a cold wall is addressed using direct numerical simulations (DNS) and wall-modelled large-eddy simulations (WMLES) at different angles of ...

The Application of the γ-Reθt Transition Model Using Sustaining Turbulence
Energies, 2022 The freestream turbulence intensity is an important parameter for Tollmien–Schlichting waves and is also used as one of the key variables for the local- and transport-equation-based transition model in the simulations.

Transitions to Electrochemical Turbulence [PDF]
Physical Review Letters, 2005 We report experimental evidence of transitions from limit cycle oscillations through a phase turbulent regime to space-time defect turbulence in a spatially (quasi-)one-dimensional electrochemical system with nonlocal coupling. The transitions are characterized in terms of the defect density, the Karhunen-Loève decomposition dimension, and a measure of

Transition to chemical turbulence [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 1991 Experiments have been conducted on Turing-type chemical spatial patterns and their variants in a quasi-two-dimensional open spatial reactor with a chlorite–iodide–malonic acid reaction. A variety of stationary spatial structures−hexagons, stripes, and mixed states−were observed, and transitions to these states were studied.

Transition to Turbulent Dynamo Saturation [PDF]
Physical Review Letters, 2017 While the saturated magnetic energy is independent of viscosity in dynamo experiments, it remains viscosity-dependent in state-of-the-art 3D direct numerical simulations (DNS). Extrapolating such viscous scaling-laws to realistic parameter values leads to an underestimation of the magnetic energy by several orders of magnitude.
