چکیده:

In the present investigation, numerical simulations were performed to study flow through converging two-dimensional plates. The flow was considered to be laminar, steady and incompressible. The influences of Reynolds number and converging angle of plates on the pressure drop, friction factor, centerline velocity and velocity profile in developing and fully developed regions were studied. The set of governing dimensionless equations with appropriate boundary conditions were solved together using numerical finite volume method. Results indicate that as the plates converging angle increases the dimensionless pressure drop, friction factor and centerline velocity increase. Also increasing the Reynolds number increases the wall velocity gradient and entrance hydrodynamic length.
