Description 182-192
This article investigates the nanoflow with base fluid as Williamson along a circular cylinder incorporating non-linear energy
generation/absorption embedded in a porous media. The obeying boundary layer balances for flow field, energy and diffusion
transfer are modelled under Boussinesq approximation. Dimensional partial differential equations have been converted to
dimensionless partial differential equations by adaptable non-similar variables. Obtained partial differential equations have been
handled by Thomas algorithm of solving partial differential equations. It is finite difference method usually named as Keller box
method. Varied fluid parameters like Williamson, porous, radiation, heat source/sink, buoyancy ratio and inertial force parameter
characteristics on the flow field are graphically illustrated. Additionally, shear friction, heat and mass transfer rate have been
estimated for the flow control parameters. Stream wise velocity improves, the skin friction coefficient decreases. As non-uniform
heat generation parameter improves, the energy transfer rate and friction factor increase since more heat transfer from the wall have
been absorbed by the fluid. Concentration rate near the cylinder wall decreases as energy producing is more in the fluid.
