Mathematical analysis of MHD stagnation point flow of Cu-blood nanofluid past an exponential stretchable surface

Two dimensional, steady, incompressible magnetohydrodynamic flow near a stagnation region toward an exponentially stretching plate is numerically investigated in present illustration. Base fluid- blood, along with copper (Cu) is taken to compose the nanofluid and different shapes of nanoparticles such as sphere, hexahedron, tetrahedron, column and lamina are taken into considerations. By using the suitable similarity transformations, the consequent equations are converted to a set of nonlinear ordinary differential equations. The spectral relaxation method is applied to compute the solution of the system. Several parameters like stretching parameter, nanoparticle volume fraction, magnetic parameter, Brinkman number and empirical shape factor are emerging in the governing equations, which affects the fluid flow veocity and temperature. These changes are given in the graphical form. Furthermore, impacts of specified parameters on surface shear stress and surface heat flux are also enlisted in form of tables. To ensure the validation of the results, the present results are compared with already existing data.
