Abstract
This article unveils the combined impact of heat generation/absorption and Joule
heating on MHD flow of Ag-H2O nanofluid into a porous stretching/shrinking divergent/
convergent channel with viscous dissipation and solid volume fraction. The mathematical
modeling is presented for the existing equations of continuity, momentum, and energy
fraction. The reduced boundary value problem is solved numerically employing RungeKutta-Fehlberg (RKF) method via shooting scheme and then the outcomes are sketched
and interpreted. The results explore that the thermal boundary layer thickness of the
stretching divergent and the shrinking divergent channels enhance by increasing the
value of the Eckert number, while the opposite tendency is scrutinized on the
momentum boundary layer thickness by increasing the value of the porosity parameter
for the stretching divergent and the shrinking convergent channels.
