Bifurcation of blood flow in a planar contraction channel can be compared with mitral valve regurgitation. Mitral regurgitation is leakage of blood in backward direction through the mitral valve when the left ventricle contracts. During the contraction a leaking mitral valve allows to flow in two directions: (i) some blood flows through the aortic valve from the ventricle, (ii) some blood flow backs into the atrium, which can cause heart attack. In this work we focused on detailed numerical analysis of the flow in a planar contraction-expansion channel. The flow configuration is very useful in many industrial applications for example mixing devices, biomedical instruments etc. The focus of this study is two folded: (i) Sudden contraction of fluid flow through an narrow open channel has been analyzed numerically using commercial CFD tools with different low Reynolds number, (ii) Analysis of blood blockage in mitral valve.
