Magnetohydrodynamic go-water nanofluid flow and heat transfer between two parallel moving disks

Abstract

The unsteady MHD squeezing flow of nanofluid with different type of nanoparticles between two parallel disks is discussed. The governing equations, continuity, momentum, energy, and concentration for this problem are reduced to coupled non-linear equations by using a similarity transformation. It has been found that for contracting motion of upper disk combined with suction at lower disk, effects of increasing absolute values of squeeze parameter are quite opposite to the case of expanding motion. In this case, radial velocity near upper disk decreases while near the lower disk an accelerated radial flow is observed. The comparison between analytical results and numerical ones achieved by forth order Runge-Kutta method, assures us about the validity and accuracy of problem.

The 2-D Cu-water nanofluid-flow and heat transfer over an inclined wall and between two inclined walls: The numerical solution of PDE and ODE

“…The working nanofluid is a water based nanofluid and its solid volume fraction is φ. The physical properties, such as density and the kinematic viscosity [6], and thermal properties, such as thermal conductivity [7] of the nanofluid can be defined: Introducing η = θ/α and f(θ) = ru(r, θ) the velocity parameters dimensionless form can be obtained by dividing to its maximum values,…”

“…The thermal performance of a small heat sink thermoelectric cooling module using water-based nanofluid is explored experimentally in a work by Wiriyasart et al [5]. Azimi and Riazi [6] investigated a situation of nanofluid-flow between two spinning disks for unstable nanofluid-flows.…”
