Key result
Bingham plastic fluid models show flux, shear stress, and flow resistance vary with stenosis height.
This mathematical model provides theoretical insights into how stenosis height affects blood flow dynamics when blood is modeled as a Bingham plastic fluid.
No immediate clinical implications; leaves open validation of Bingham plastic models for stenotic hemodynamics.
A mathematical model for blood flow through an axially symmetric but radially non- symmetric stenosed artery has been considered. The effect of non-Newtonian nature of blood has been taken into account by modelling blood as a Bingham plastic fluid. Variation of flux, wall shear stress , resistance to flow with different stenosis height has been incorporated. The results are shown graphically and discussed.

A 2014 study studied Arterial stenosis. Stenosis height variation in a Bingham plastic fluid model was evaluated on Variation of flux, wall shear stress, and resistance to flow. A mathematical model of blood as a Bingham plastic fluid demonstrated that flux, wall shear stress, and resistance to flow vary with different stenosis heights.
