Distribution of pressure gradient 𝑑𝑝/𝑑𝑥 with 𝑥 for different values of Hall parameter 𝑚 (a), amplitudes of right wave 𝑎 (b), left wave 𝑏 (c), and the nondimensional heat source/sink parameter 𝛽 (d). The other parameters chosen are 𝐹=−5, 𝑦=1, 𝑑=1, 𝑀=1.2, 𝑎=0.4, 𝑏=0.2, 𝛽=2, 𝑘=1, 𝜙=𝜋/4, Gr=3 (a); 𝐹=−5, 𝑦=1, 𝑑=1, 𝑀=1.2, 𝑚=0.5, 𝑏=0.2, 𝛽=2, 𝑘=1, 𝜙=𝜋/4, Gr=3 (b); 𝐹=−5, 𝑦=1, 𝑑=1, 𝑀=1.2, 𝑚=0.5, 𝑎=0.4, 𝛽=2, 𝑘=1, 𝜙=𝜋/4, Gr=3 (c); 𝐹=−5, 𝑦=1, 𝑑=1, 𝑀=1.2, 𝑚=0.5, 𝑎=0.4, 𝑏=0.2, 𝑘=1, 𝜙=𝜋/4, Gr=3 (d).
