The hydrodynamic entrance region refers to the area of a pipe where fluid entering a pipe develops a velocity profile due to viscous forces propagating from the interior wall of a pipe. This region is characterized by a non-uniform flow. The fluid enters a pipe at a uniform velocity, then fluid particles in the layer in contact with the surface of the pipe come to a complete stop due to the no-sli… WebLAB 6 - Flow Through a Circular Pipe Introduction In any viscous flow, the fluid in direct contact with a solid boundary has the same velocity as the boundary itself and the "no-slip condition" must be satisfied at the boundary. Since the fluid velocity at the stationary solid surface is zero, but the bulk fluid is moving, velocity gradients ...

WebBased on the two-dimensional hydrodynamic model of the finite volume method and structured multigrid, the flow characteristics around a square cylinder with boundary constraint are analysed.
