Figure 9

The variation of friction force at the right wall 𝐹_𝜆1 with Θ for different values of Hall parameter 𝑚 (a), porosity parameter 𝑘 (b), Grashof number Gr (c), and nondimensional heat source/sink parameter 𝛽 (d). The other parameters chosen are 𝑑=1, 𝑀=1.2, 𝑎=0.1, 𝑏=0.2, 𝜙=𝜋/2, 𝑘=1, 𝛽=2, Gr=3 (a); 𝑑=1, 𝑀=1.2, 𝑎=0.1, 𝑏=0.2, 𝜙=𝜋/2, 𝑚=0.5, 𝛽=2, Gr=3 (b); 𝑑=1,𝑀=1.2, 𝑎=0.1, 𝑏=0.2, 𝜙=𝜋/2, 𝑘=1, 𝑚=0.5, Gr=3 (c); 𝑑=1, 𝑀=1.2, 𝑎=0.1, 𝑏=0.2, 𝜙=𝜋/2, 𝑘=1, 𝛽=2, 𝑚=0.5 (d).
