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

Abstract In this article, three-dimensional squeezing flow of nanofluid in a channel is presented. The lower wall of the channel is assumed to be stationary but permeable. The governing equations for the problem are transformed into a set of nonlinear equations. Solution of the resulting equations is obtained by employing a numerical procedure called Runge-Kutta-Fehlberg (RKF) method. Water is taken as the base fluid and is assumed to be suspended by Carbon Nanotubes (CNT). Two types of nanoparticles namely, Single Wall Carbon Nanotubes (SWCNT) and the Multi Wall Carbon Nanotubes (MWCNT) are considered for the analysis. Influence of pertinent parameters on velocity and temperature profiles are highlighted graphically coupled with comprehensive discussions. Expressions for skin friction coefficient and the Nusselt number are also derived and variations in these quantities are graphically demonstrated. Further, a comparison of current solutions with already existing ones is also provided.
