Mathematical analysis of dispersion of solutes in blood flow using herschel-bulkley fluid model through an inclined uniform artery

his study aims to analyse the effect of inclination of the artery on the blood velocity and solute dispersion in an artery when it is inclined to a certain angle. Herschel-Bulkley fluid model is considered in representing the blood flow. The method of integration and perturbation are used to obtain...
