Overview

Analysis reveals that stability is influenced by the Darcy number in triple-diffusive convection, suggesting potential subcritical bifurcations.

Key Points

  • This research aims to investigate the stability of triple-diffusive convection in a porous medium saturated with a Voigt fluid.
  • Conducted linear and weakly nonlinear stability analysis.
  • Analyzed the influence of the Kelvin–Voigt parameter on convection.
  • Quantified heat and mass transport using Nusselt and Sherwood numbers.
  • Identified oscillatory convection influenced by the solute Darcy–Rayleigh number.
  • Found that Darcy number and effective heat capacity group affect transport characteristics.
  • Revealed the emergence of subcritical bifurcations under certain conditions.
