Question
Question 1: Consider fully developed two-dimensional Poiseuille flow: flow between two infinite
parallel plates separated by distance h, with both the top plate and bottom plate stationary, and a
forced pressure gradient dP/dx driving the flow as
illustrated in the figure (dP/dx is constant and
negative). The flow is steady, incompressible, and
two-dimensional in the xy-plane. The velocity
components are given by
1 dP
u(y)
u =
2μ dx
(y²hy); v = 0
where is the fluid's viscosity. Is this flow rotational or irrotational?
a. If it is rotational, calculate the vorticity component in the z-direction. Do fluid particles in this
flow rotate clockwise or counterclockwise?
b. calculate the linear strain rates in the x- and y-directions, and
c. calculate the shear strain rate ɛxy.
d. Combine your results to form the two-dimensional strain rate tensor εij in the xy-plane,
