Intestinal flow of a couple stress nanofluid in arteries.

The current article discusses the influence of nanofluid on the peristaltic flow of an incompressible couple stress fluid in a two-dimensional uniform tube. The problem formulation is accessible in an upsurge structure of orientation for equations of momentum, energy, and concentrations. The continuity, linear momentum, energy, and nanoparticle equations lead to the mathematical development. HPM is used to get the solutions for velocity, temperature, nanoparticle, and pressure gradient. The solutions contain the Brownian motion number N(b), thermophoresis number N(t), local temperature Grashof number B(r), and local nanoparticle Grashof number G(r). The physical features of different embedded parameters are analyzed and discussed physically in detail.
