The MHD graphene nanofluid flow between two stretching discs

Abstract

Consider a two-dimensional steady axisymmetric flow of an incompressible fluid with graphene nanoparticles between two infinite stretching discs with accelerated velocity and a magnetic field of strength $B_0$ is applied to the flow at the angle $\tau$. The similarity transformation technique is adopted to find the analytical solution for the considered Navier–Stokes equation presented in a cylindrical coordinate form. The exact solution is analysed for the effect of stretching the Reynolds number and stretching velocity ratio. Pressure is high at the upper disc than at the lower disc when the stretching velocity ratio is less than unity. Then the effect of inclined MHD on the 2-D flow between stretching sheet discs yielding the solution in terms of an analytical method. The potential applications of these problems are used in the field of engineering and medical field, such as cancer tumour treatment and magnetic devices for cell separation.
