This module is drawn from MAE 4230/5230 Intermediate Fluid Dynamics&nb= sp;at Cornell University.
Consider fluid flowing through a circular pi= pe of constant radius as illustrated below. The figure is not to scale= . The pipe diameter D =3D 0.2 m and length L =3D 3 m Consider the inlet velocity to be constant over the cr= oss-section and equal to 1 m/s.= The pressure at the pipe outlet is 1 atm. Take density =CF= =81 =3D 1 kg/ m 3 and coefficient of viscosity = ;=C2=B5 =3D 2 x 10 -3 kg/(m*s). T= hese parameters have been chosen to get a desired Reynolds number of 100 an= d don't correspond to any real fluid.
We'll solve this problem numerically using A= NSYS Fluent. We'll look at the following results:
Velocity vectors
Velocity magnitude contours
Pressure contours
Velocity profile at the outlet
We'll verify the results by following a syst= ematic process which includes comparing the results with the analytical sol= ution in the full-developed region.
