Hall Currents and Heat Transfer Effects on Peristaltic Transport in a Vertical Asymmetric Channel through a Porous Medium

Figure 11

The variation of heat transfer coefficient 𝑍 with 𝑥 for different values of amplitude of the left wave 𝑏 (a), channel width 𝑑 (b), phase angle 𝜙 (c), and nondimensional heat source/sink parameter 𝛽 (d). The other parameters chosen are 𝑑=1, 𝑎=0.4, 𝛽=−4, 𝜙=𝜋/4 (a); 𝑎=0.4, 𝑏=0.3, 𝛽=−4, 𝜙=𝜋/4 (b); 𝑏=0.3, 𝑎=0.4, 𝛽=−4, 𝑑=1 (c); 𝑑=1, 𝑎=0.4, 𝜙=𝜋/4, 𝑏=0.2 (d).
