Abstract
In this article, the stagnation point flow of an incompressible Au–blood fluid over a stretching sheet in porous medium is examined with suction/injection and Cattaneo–Christov effects. The transformed ODEs are solved numerically by the shooting-based bvp4c method with MATLAB software. The flow phenomenon is influenced by thermal relaxation with slip boundary conditions. The shape of gold (Au) nanoparticle is considered as: cylindrical, platelet, and blade, and the Hamilton–Crosser model of thermal conductivity is taken. The Casson parameter increases the nanofluid velocity and decreases the fluid temperature. The increment in the thermal relaxation parameter increases the fluid temperature profiles. The particle shape can also enhance the temperature. The nanoparticles of blade shape have huge influences on temperature rise due to greater thermal properties. A comparative analysis is made in accordance with previous works and is in good agreement.
