Natural Convection in A Nanofluid Layer with Feedback Control Strategy
This work deals with the theoretical investigation on the effect of feedback control in a nanofluid layer on
natural convection. The partial differential equations involved in the problem are solved by asymptotic approximations and
the nanoparticles components are computed analytically and discussed graphically for various values of feedback control
using Galerkin method. There are three types of boundaries that are considered in this investigation namely free-free, rigidfree
and rigid-rigid boundaries which defined the lower-upper boundaries. It is found that an increase of the feedback control
suppress the onset of natural convection in nanofluid layer and the nanofluid parameters have a significant effect on the
thermal stability in the system.
