Blood stream alternations by mean of electroosmotic forces of fractional ternary nanofluid through the oblique stenosed aneurysmal artery with slip conditions

Abstract

Aneurysm or stenosis in an artery is not very common, but it is becoming increasingly recognized due to its high incidence in pediatric and young adult patient. In the present study, a fractional second-grade fluid model with ternary nano-particles (Cu, Ag, CuO) is implemented to investigate the effects of electroosmotic forces (EMHD) through an oblique stenosed aneurysmal artery. The mild stenotic supposition is used to normalize and reduce the two directional momentum equations to the unidirectional flow. Closed-form solutions are calculated for the situation of mild stenosis and aneurysm by solving the governing equations for the suggested paradigm. Graphs are used to illustrate the effects of nanoparticles and aneurysm on blood flow rate, wall shear stress, and impedance. The results of ternary nanoparticles (Cu-Ag-CuO /blood), hybrid nanoparticles (Cu-Ag/blood), and copper (Cu) nanoparticles have also been compared, and this comparison suggests that ternary nanoparticles (Cu-Ag-CuO/blood) are more effective at attenuating hemodynamic factors (such as wall shear stress and impedance) than hybrid and copper (Cu) nanoparticles. Through the streamlines for various emerging parameters, the general behaviour of the blood flow patterns is also seen. The present study findings are particularly helpful for drug transportation and biomedical research.
