Nonlinear Fluid Models for Biofluid Flow in Constricted Blood Vessels under Body Accelerations: A Comparative Study

Table 1

Estimates of the increase in the longitudinal impedance to flow due to the increase in the stenosis shape parameter and body acceleration with δ = θ = 0.1, e = 0.5, ω = 1, 𝛼_𝐻 = 𝛼_𝐶 = ϕ = 0.2, z = 4, and t = 60°.
