Laminar-Turbulent Patterns in Shear Flows : Evasion of Tipping, Saddle-Loop Bifurcation and Log scaling of the Turbulent Fraction
Pavan V. Kashyap, Juan F. Marìn, Yohann Duguet +1
We analyze a one-dimensional two-scalar fields reaction advection diffusion model for the globally subcritical transition to turbulence. In this model, the homogeneous turbulent st…
Linear stability of turbulent channel flow with one-point closure
P. V. Kashyap, Y. Duguet, O. Dauchot
For low enough flow rates, turbulent channel flow displays spatial modulations of large wavelengths. This phenomenon has recently been interpreted as a linear instability of the tu…
Linear instability of turbulent channel flow
Pavan V. Kashyap, Yohann Duguet, Olivier Dauchot
Laminar-turbulent pattern formation is a distinctive feature of the intermittency regime in subcritical plane shear flows. By performing extensive numerical simulations of the plan…
Flow Statistics in the Transitional Regime of Plane Channel Flow
Pavan V. Kashyap, Yohann Duguet, Olivier Dauchot
The transitional regime of plane channel flow is investigated {above} the transitional point below which turbulence is not sustained, using direct numerical simulation in large dom…
Far field of turbulent spots
Pavan V. Kashyap, Yohann Duguet, Matthew Chantry
The proliferation of turbulence in subcritical wall-bounded shear flows involves spatially localised coherent structures. Turbulent spots correspond to finite-time nonlinear respon…
