Thermal instability of rotating nanofluid layer
TL;DR: In this paper, the authors considered thermal instability of rotating nanofluids heated from below and made a linear stability analysis to investigate analytically the effect of rotation on the onset of convection.

Magneto convection in a nanofluid layer
TL;DR: In this article, a linear stability analysis for the onset of convection in a nanofluid layer with magnetic field is presented, and it is established that the instability is almost purely a phenomenon due to buoyancy coupled with the conservation of nanoparticles.

Thermal convection in micropolar fluids in porous medium
R. C. Sharma,Urvashi Gupta +1 more
TL;DR: In this article, the effect of medium permeability on thermal convection in micropolar fluids is considered and it is found that the presence of coupling between thermal and micro-fluid effects may introduce oscillatory motions in the system.

Kinematic and static hypotheses for constitutive modelling of granulates considering particle rotation
Ching S. Chang,J. Gao +1 more
TL;DR: In this paper, the macro-scale constitutive law for a granular material is derived from the micro-scale of two interacting particles, and the effects of inter-particle stiffness on the macro scale constitutive constants are discussed.

Convection in a box: linear theory
TL;DR: In this article, the linear stability of a quiescent, three-dimensional rectangular box of fluid heated from below is considered and the value of critical Rayleigh number and preferred wave number for a given size box is determined for boxes with horizontal dimensions h, ¼ ≤ h/d ≤ 6, where d is the depth.
