Slip effects on 3-D spinning dual-phase nanofluid flow over an exponentially stretching sheet with variable viscosity

Abstract

This article's major goal is to describe the slip boundary condition and movement of a rotating, three-dimensional, steady flow of nanoparticles across a flexible surface. The dual-phase concept of nanofluid is utilized in physically existing models. The partial differential governing equations are split into ordinary differential equations by utilizing similarity transformations. The built-in solver bvp4c in MATLAB is used to evaluate the statistical solution. This study shows that velocity and temperature profiles depend on basic variables such as slip parameter, variable viscosity, stretching ratio, and rotation parameter. Tables display the numeric value of several parameters related to the Nusselt number and skin friction indices. Copper oxide and silver nanoparticles in a water base fluid are utilized for examination. According to the graphical representation, the variable viscosity parameter's velocity profile is growing while the slip parameter's decreasing and the temperature profile inclining for the slip parameter while declining for variable viscosity.
