MHD FLOW INSIDE A STRETCHING/SHRINKING CONVERGENT/DIVERGENT CHANNEL WITH HEAT GENERATION/ABSORPTION AND VISCOUS-OHMIC DISSIPATION UTILIZING CU−WATER NANOFLUID
SINOPSIS
The goal of the present study is to analyze the magnetohydrodynamic flow of Cu−water nanofluid between two stretchable/shrinking channels due to the effects of heat generation/absorption, viscous dissipation, and Ohmic heating. The model of thermal conductivity and dynamic viscosity is based on the spherical shape of nanoparticles. The numerical method Runge−Kutta−Fehlberg fourth- to fifth-order scheme has been employed with a shooting scheme to solve the transformed ordinary differential equations. The numerical solution of several dominant parameters, that is, heat generation/absorption parameter, magnetic field parameter, and Eckert number, are obtained. The results signify that velocity profiles of stretching divergent channels decrease with a boost in Hartmann number, while for the same case, temperature curves constantly enhance. The shear stress rate is augmented with Hartmann number for stretching convergent/divergent channels. An admirable agreement has been noticed on comparing present results with earlier studies.
