The present research investigates the impact of arterial inclination and body acceleration force on the blood flow and solute dispersion through a stenosed artery using the Bingham model as a representation of the blood rheology. The problem is formulated using the momentum equation with the presence of inclination and body force acceleration param...

Motivated by the concept of blood flow in a stenosed artery, this present research investigates the influence of stenosis shape in terms of height and arterial inclination on the blood flow and solute dispersion behaviour through an inclined stenosed artery.

The set of PDEs were overhaul into a nonlinear ordinary differential equation by considering acceptable similarity variable. T...

The presence of stenosis at the wall of the artery lead to further cardiovascular diseases such as heart attack, stroke and many more.

Blockage of blood flow due to cholesterol deposits at the arterial wall, known as stenosis, can lead to conditions such as heart attack and stroke. Treatment such as balloon angioplasty involves the catheterization of an artery where a stented catheter is inflated at the stenosis site to open the narrowed artery. The catheterization of the stenosed...

One major kind of arterial disease in blood flow that attracted many researchers is arterial stenosis. Arterial stenosis occurs when a lumen of artery is narrowed by the accumulation of fats, cholesterols and lipids plaques at the inner layer of the wall of an artery.
