The objective of the manuscript is to find the effect of cosine shape stenosis on different physical properties such as skin friction, resistance to flow, and flow rate of the stenosed artery. The Casson fluid is a thin shear fluid at high viscosity, and blood can be considered an example of Casson fluid. Numerical computation for different flow quantities normalized with Newtonian and non-Newtonian fluid has been done with the help of the two-point Gauss quadrature formula. The normalized flow resistance with Newtonian fluid increases with stenosis depth. However, normalized flow resistance with non-Newtonian fluid reduces by enhancement of yield stress. The normalized skin friction with Newtonian fluid is increased by increasing the yield stress value; normalized skin friction with non-Newtonian fluid is highest at stenosis throat, and lowest at the artery ends.
