White, Viscous Fluid Flow, McGraw-Hill Book Co., Inc., New York, NY, 1991, Section 3-2.3. Analysis Type(s): Fluid, Flow Analysis (FLOTRAN) Element Type(s): 3-D Fluid-Thermal Element (FLUID142) Input Listing: vm46.dat Test Case Consider the steady flow maintained between two infinite concentric cylinders by a constant angular velocity of the inner cylinder while the outer cylinder remains fixed. Determine the velocity distribution between the two cylinders using a rotating reference frame attached to the inner cylinder.
