Flow through Pipe with a Sudden Contraction in Laminar Region

application/pdf
Numerical solutions of the Navier-Stokes equation for the axi-symmetric flow through a pipe with a sudden contraction (contraction ratio=1/2) are described. The numerical solutions, for Reynolds numbers ranging from 50 to 10,000, are obtained by using an upwind-difference scheme. The results are presented for pressure distribution, shear stress distribution, separation condition and so on, in front of the contraction. They are similar to those of a two dimensional flow over a forward facing-step. In this flow type, a certain separation condition is found in the Reynolds number region from 500 to 2300. A finite front eddy can be expected to exist at the limit as the Reynolds number approaches to zero.
