Laminar Pipe Flow

Created using ANSYS 13.0. Tutorial instructions work with ANSYS 14.0 and 15.0. There are minor layout changes in ANSYS 15.0. 

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. Present the following results:

• Velocity vectors 
• Velocity magnitude contours 
• Pressure contours 
• Velocity profile at the outlet
• Skin friction coefficient along the wall

Provide comparisons of the results with the full-developed analytical solution. Verify your results.
