A phenomenology of isotropic magnetohydrodynamic (MHD) turbulence subject to both rotation and applied magnetic field is presented. It is assumed that the triple correlation decay time is the shortest between the eddy turn-over time and the ones associated to the rotating frequency and the Alfvén wave period. For Pm=1 it leads to four kinds of piecewise spectra, depending on four parameters: in...

Abstract Nanofluids have many applications in industries as well engineering such biomedicine, manufacturing, and electronics. Nanofluid is used for improvement of thermal mass transmission. Based on the aforementioned applications, present study, a two-dimensional Maxwell nanofluid with radiation effect existence motile microorganisms over vertically stretchable surface explored. The consequen...

The steady flow of a Reiner-Rivlin fluid with Joule heating and viscous dissipation is studied. We present a novel technique for accelerating the convergence of the spectral-homotopy analysis method. Solutions of the nonlinear momentum and energy equations are obtained using the improved spectral homotopy analysis method. Solutions were also generated using the spectral-homotopy analysis method...

Soft glassy materials made of deformable cells, such as liquid foams, simultaneously display elastic, plastic and viscous behaviours. Bubble deformation is elastic until the material plastically yields and bubbles swap neighbours, then bubbles relax dissipatively towards a new energy minimum. This relaxation occurs in a finite time, and shearing a foam at a fast strain rate compared to that tim...

We examine the changes in kinetic energy dissipation of a turbulent channel flow caused by a spanwise magnetic field. The numerical study is based on our simulation data from [1] obtained by direct and large eddy simulations. We find that the Joule dissipation can exceed the viscous dissipation in the weakly dissipative bulk region, but remains comparatively small in the turbulence-generating n...

In this paper, we investigate the solvability, regularity and vanishing dissipation limit of solutions to three-dimensional viscous magnetohydrodynamic (MHD) equations in bounded domains. On boundary, velocity field fulfills a Navier-slip condition, while magnetic satisfies insulating condition. It is shown that initial boundary value problem has global weak solution for general smooth domain. ...
