1. For a pulsating blood flow (μ = 3.25cP and ρ = 1.05g/cm3) in a dog aorta of diameter 1.5 cm at 120 cm/sec mean velocity and 4π/sec oscillating frequency. (a) Find Reynolds number, Stokes number and Womersly number. (b) Discuss the relative importance between the transient inertial force, convective inertia force, and viscous force. 2. Consider a type of 2-D incompressible unsteady-flow between two parallel surfaces apart by h, as shown in the figure. The surface y = 0 is held fixed while the surface y = h is oscillating in the x direction with a velocity U = U0cosωt, where ω is the frequency. Assume that the fluid viscosity is μ and density is ρ. Solve the velocity u = u(y, t) from the Navier-Stokes equations

1. For a pulsating blood flow (µ = 3.25cP and ρ = 1.05g/cm3) in a dog aorta of diameter
1.5 cm at 120 cm/sec mean velocity and 4π/sec oscillating frequency.
(a) Find Reynolds number, Stokes number and Womersly number.
(b) Discuss the relative importance between the transient inertial force, convective inertia
force, and viscous force.
2. Consider a type of 2-D incompressible
unsteady-flow between two parallel surfaces
apart by h, as shown in the figure. The
surface y = 0 is held fixed while the surface
y = h is oscillating in the x direction with a
velocity U = U0cosωt, where ω is the
frequency. Assume that the fluid viscosity is
µ and density is ρ. Solve the velocity u =
u(y, t) from the Navier-Stokes equations.
