Exercise 2: Laminar Flow within Two Concentric Cylinders

Contributed by Prof. John Cimbala and Matthew Erdman, Pennsylvania State University

This problem considers the flow of an incompressible Newtonian liquid that is confined between two concentric circular cylinders of infinite length. See this pdf file for the problem statement. The video below shows how to use ANSYS Fluent to set up and solve a problem like this.

Exercise 3: Laminar Pipe Flow

Consider developing flow in a pipe of length L = 8 m, diameter D = 0.2 m, ρ = 1 kg/m3 , µ =2 × 10^−3 kg/m s, and entrance velocity u_in = 1 m/s (the conditions specified in the Problem Specification section). Use FLUENT with the "second-order upwind" scheme for momentum to solve for the flowfield on meshes of 100 × 5, 100 × 10 and 100 × 20 (axial divisions × radial divisions).
