Laminar Pipe Flow

Created using ANSYS 13.0

Problem Specification



Consider fluid flowing through a circular pipe of constant radius as illustrated above. The figure is not to scale. The pipe diameter D = 0.2 m and length L = 8 m Consider the inlet velocity to be constant over the cross-section and equal to 1 m/s. The pressure at the pipe outlet is 1 atm. Take density ρ = 1 kg/ m3 and coefficient of viscosity µ = 2 x 10-3 kg/(m s). These parameters have been chosen to get a desired Reynolds number of 100 and don't correspond to any real fluid. 

Solve this problem numerically using ANSYS FLUENT. Plot the velocity and pressure variation within the pipe. Verify your results.
