ABSTRACT: The laminar flow in the entrance region of pipes having a circular cross
section is investigated by the use of finite element solutions to the full
Navier-Stokes equations in cylindrical coordinates. Because these solutions
cover the complete three-dimensional geometry the usual development length is
no longer a very interesting parameter as explained herein. The velocities and
pressures are determined throughout the pipe and presented in graphic form.
