Summary

The Navier-Stokes equations are solved in two and three dimensional problems using the program FEMLAB. Both laminar and turbulent flow are considered, although the turbulent flow problems are only simple ones. Problems include developing flow in pipe, start-up flow in a pipe, flow of a non-Newtonian fluid, flow in a T-sensor, flow in an orifice, and flow in a serpentine mixer. The identification of proper boundary conditions is summarized. Examples show how to make the equations dimensionless.
