Peristaltic Flow of a Nanofluid under the Effect of Hall Current and Porous Medium

Figure 8

Streamlines for two different values of local temperature Grashof number 𝐺_𝑟 (panels a, b) and two different values of porosity parameter 𝑠 (panels c, d). The other parameters chosen are 𝑄=2, 𝑑=1, 𝑀=1.2, 𝑎=0.3, 𝑏=0.5, 𝑁_𝑏=0.8, 𝑁_𝑡=0.5, 𝑠=0.5, 𝜙=0.02, 𝑚=1, and 𝐵_𝑟=0.5 (panels a, b); 𝑄=2, 𝑑=1, 𝑀=1.2, 𝑎=0.3, 𝑏=0.5, 𝑁_𝑏=0.8, 𝑁_𝑡=0.5, 𝑚=1, 𝜙=0.02, 𝐺_𝑟=0.5, and 𝐵_𝑟=0.5 (panels c, d).
