Nonlinear Magnetoconvection in a Sparsely Packed Porous Medium

Figure 7

Figures (a–d), are plotted for Pr₂/Pr₁=6,12,18, and 24, respectively, and for fixed parameters 𝐷_𝑎=1500, Λ=0.85, 𝜙=0.9, and 𝑀=0.9. Stability regions of steady state (SS), travelling waves (TW), and standing waves (SW) are plotted (𝑄,Pr₁)-plane.
