Unstable Convection in a Vertical Double–Layer Porous Slab

open access: yesEnergies, 2023
A convective stability analysis of the flow in a vertical fluid-saturated porous slab made of two layers with different thermophysical properties is presented. The external boundaries are isothermal with one of them impermeable while the other is open to

Simplified Mathieu’s equation with linear friction [PDF]

open access: yesINCAS Bulletin, 2016
Consider a second order differential linear periodic equation. The friction coefficient is real positive constant. Some transformation of the solution and its first derivative allow writing two-order differential equations with void friction coefficients.

Onset of Viscous Dissipation Instability in Plane Couette Flow with Temperature-Dependent Viscosity

open access: yesEnergies, 2023
The conditions for the onset of dissipation thermal instability with temperature-dependent viscosity in the plane Couette flow of a Newtonian fluid are analyzed. The studied system consists of a horizontal fluid layer confined between an adiabatic (fixed)

A revised model for the effect of nanoparticle mass flux on the thermal instability of a nanofluid layer

open access: yesDemonstratio Mathematica, 2021
A revised model of the nanoparticle mass flux is introduced and used to study the thermal instability of the Rayleigh-Benard problem for a horizontal layer of nanofluid heated from below.

Linear Stability of a Steady Convective Flow between Permeable Cylinders

open access: yesFluids, 2021
Linear stability analysis of a steady convective flow in a tall vertical annulus caused by nonlinear heat sources is conducted in the paper. Heat sources are generated as a result of a chemical reaction.

Stability of time-varying systems in the absence of strict Lyapunov functions [PDF]

open access: yes, 2019
When a non-linear system has a strict Lyapunov function, its stability can be studied using standard tools from Lyapunov stability theory. What happens when the strict condition fails?
