Key result
Mathematical models link increasing stenotic height to decreased flow velocity, concentration, and skin friction.
Why the study?
A mathematical model was needed to study pulsatile blood flow and mass transfer through a stenosed artery under body acceleration and magnetic fields.
Mathematical modeling demonstrates that magnetic fields and stenotic height significantly alter blood flow velocity and mass transfer in simulated arterial stenosis.
Extends computational models of stenotic flow under magnetic and accelerative effects; leaves open clinical relevance pending empirical validation.
A mathematical model has been developed and used to study pulsatile blood flow and mass transfer through a stenosed artery in the presence of body acceleration and magnetic fields.An explicit Finite Difference Method (FDM) has been used to discretize the formulated mathematical model.The discretized model equations were solved in MATLAB software to produce simulations.The effect of Hartman number, Reynolds number, Schmidt number, stenotic height, body acceleration and chemical reactions have been investigated.It has been observed that, the velocity, concentration and skin friction, decrease with increasing stenotic height.Velocity on the other hand increases, as body acceleration increases.It has further been observed that as the Hartman number increases, both the radial and axial velocities diminish.Increase of the Reynolds number results in the increase of the velocity profiles.The higher the chemical reaction parameter is, the lower are the concentration profiles.

Mwapinga et al. (2020) studied Stenosed artery. Magnetic fields, body acceleration, and chemical reactions was evaluated on Velocity, concentration, and skin friction. In a mathematical model of a stenosed artery, increasing stenotic height decreased velocity, concentration, and skin friction, while increasing body acceleration increased velocity.
