Study of 2-d laminar flow in a pipe with a sudden contraction of cross sectional area

الملخص EN

The paper presents a detailed numerical study of laminar flow in a pipe with sudden contraction in its cross sectional area.

A computer program has been developed to analyze the laminar flow field in the pipe-sudden contraction configuration.

The Navier-Stockes and energy equations are solved using primitive variables with a finite-volume (FV) solution method.

The study was carried out for a Reynolds numbers range up to 750 and for different contraction ratios (d / D).

The results demonstrate that the separation regions increase with the increase of Reynolds numbers.

And the contraction ratio (d / D) has significant effect on these regions.
