Mathematical Modelling of Pulsatile Flow of Non-Newtonian Fluid Through a Constricted Artery

The research work explores blood flow into a stenosed artery, or one with abnormal growth within it. At the throats and at critical height of stenosis, mathematical computational models have been developed to calculate various associated parameters such as rate, pressure gradient, impedance, wall shear stress. Modeling power law fluid showed dependency these quantities on temporal spatial variables, well frequency oscillation in time key mechanism. exponential curve is geometry stenosis studied this analysis. Analytical expressions for axial velocity, volumetric resistance, stress computed simulated ANSYS generate useful results respect variation indices also comparison between Newtonian Non- blood. Upon investigation, it was found that (WSS) increases depth therefore, plays crucial role affecting other parameters. index 0.6, highest velocity were encountered approximately 7 Pa 0.5 m/s respectively.
