The variation of the velocity distribution 𝑢 with 𝑦 for various values of Hall parameter 𝑚 (a), porosity parameter 𝑘 (b), Grashof number Gr (c), and width of the channel 𝑑 (d). The other parameters chosen are: Θ=4, 𝑥=0, 𝑑=1, 𝑀=1.2, 𝑎=0.4, 𝑏=0.2, 𝛽=2, 𝑘=1, 𝜙=𝜋/4, Gr=10 (a); Θ=4, 𝑥=0, 𝑑=1, 𝑀=1.2, 𝑎=0.4, 𝑏=0.2, 𝛽=2, 𝑚=0.5, 𝜙=𝜋/4, Gr=10 (b); Θ=4, 𝑥=0, 𝑑=1, 𝑀=1.2, 𝑎=0.4, 𝑏=0.2, 𝛽=2, 𝑚=0.5, 𝜙=𝜋/4, 𝑘=1 (c); Θ=4, 𝑥=0, 𝛽=2, 𝑀=1.2, 𝑎=0.4, 𝑏=0.2, Gr=10, 𝑚=0.5, 𝜙=𝜋/4, 𝑘=1 (d).
