An exact solution is derived to the equations of vortex electron anisotropic hydrodynamics for a plasma that is unstable against the Weibel instability driven by the electron temperature anisotropy. This solution describes saturation of the Weibel instability in the single-mode regime with an...

Excitation of zonal flow by the modulational instability in the presence of mean shear flow is considered. The presence of the mean flow without large amplitude increases the modulational instability growth rate and favors zonal flow generation, whereas sufficiently strong mean shear...

We consider the influence of slip boundary conditions on the modal and nonmodal stability of pressure-driven channel flows. In accordance with previous results by Gersting [“Hydrodynamic stability of plane porous slip flow,†Phys. Fluids 17, 2126 (1974)] but in contradiction with the...

Direct numerical simulation (DNS) and large-eddy simulation (LES) of particle-laden turbulent channel flow, in which the particles experience a drag force, are investigated for two subgrid models and several Reynolds and Stokes numbers. In this flow, turbophoresis leads to an accumulation of...

A new method to derive the nonlinear equations linearized using the substitutions extending the Cole-Hopf substitution to the Burgers equation is considered. A method to analyze the general structure of the solutions and to calculate the exact solutions in the problems of one-dimensional...

We apply the Hilbert transform to the physics of internal waves in two-dimensional fluids. Using this demodulation technique, we can discriminate internal waves propagating in different directions: This is very helpful in answering several fundamental questions in the context of internal waves....
