The purpose of the present paper is to investigate the pattern formation and secondary
instabilities, including Eckhaus instability and zigzag instability, of an activator–inhibitor …

A review of publications on stability of mechanical equilibrium of multicomponent mixtures in
gases and liquids under non‐isothermal and isothermal conditions is given. Studies where …

The effect of variable gravity on rotating convection in a sparsely packed porous layer is
studied numerically. For gravity force variation, the linear, parabolic, cubic, and exponential …

The effects of Soret and Dufour parameters on the thermosolutal convection in a horizontal
couple stress fluid layer with constant temperature and solutal concentration are …

The effect of rotation and cross-diffusion on convection in a horizontal sparsely packed
porous layer in a thermally conducting fluid is studied using linear stability theory. The …

composed of two materials varying continuously according to the power-law along the radial …

The present investigation is aimed to study the joint effect of the variable gravity field and
chemical reaction on the onset of convection in a sparsely packed porous layer. Linear …

The paper investigates the impact of cross-diffusion on triple-diffusive convection in a bi-
viscous Bingham fluid layer. Non-linear stability analysis is performed, and the expression of …

Numerous disciplines, including fluid dynamics, heat transfer, geophysics, materials
science, and environmental engineering, use Rayleigh numbers, both thermal and solute …

In this paper, the effect of three different types of time-periodic gravity modulation
(trigonometric sine, triangular, and square waveforms) on rotating Rayleigh-Bénard …
