description |
The developing laminar flow in the entrance and disturbed regions of concentric circular pipes has been studied numerically. Both main pipe and disturbed pipe are concentric and stationary. Uniform developing flow occurs in entrance region of main pipe and inside disturbed pipe at disturbed region. while non-uniform developing flow occurs in annular concentric disturbed pipe at disturbed region. For the two-dimensional problem, numerical solutions are obtained for a wide range of Reynolds number from 25 to 375. A computer program and AutoFEA software were used to calculate the velocity and pressure drop within the entire channel. The maximum velocity at the centerline of the pipe, hydrodynamic boundary layer developed faster for the lower Reynolds number. However, the flow field is similar for all studied cases. All the present work data are in good agreement with AutoFEA software.
