✦ Synopsis

= radial position rl, r2 = inner and outer radii of the annulus r H = ( r 2 -r l ) / 2 = hydraulic radius Re = Reynoldsnumber u = local velocity in the x direction u, = maximum velocity in the entrance region Umf = maximum velocity in the fully developed flow = average velocity Ws = ( u / K ) ( < u > / T H ) ~-~, Weissenberg number x = axial distance measured from the contraction x 8 + T = shearstress plane = x/rHRe, dimensionless axial distance = Ws/Re = elasticity number = elastic force/iner-= -du/dr, shear rate in steady shear flow tial force
