On heat and mass transfer analysis for the flow of a nanofluid between rotating parallel plates

TL;DR: In this paper, the authors have considered the three dimensional heat and mass transfer with magnetic effects for the flow of a nanofluid between two parallel plates in a rotating system and applied Homotopy Analysis Method (HAM) to see the validity of analytical solution, a numerical solution using RK-4 method coupled with shooting method has also been sought Both the solutions are found to be in excellent agreement to capture the effects of involved physical parameters graphical representation of the flow are included with comprehensive discussions.
Journal ArticleDOI

Numerical investigation for three dimensional squeezing flow of nanofluid in a rotating channel with lower stretching wall suspended by carbon nanotubes

TL;DR: In this paper, a three-dimensional squeezing flow of nanofluid in a channel is presented, where the lower wall of the channel is assumed to be stationary but permeable.
Journal ArticleDOI
