“…Table 1 illustrates the effects of Hartmann number on the squeezing flow of nanofluid. The comparison of approximate (analytical) results [17] with numerical solutions obtained by fourth order Runge-Kutta, in the current study, have been also presented in case A = −1, S = −1, Nb = 2, Nt = 0.1, Le = 1, Pr = 6.2.…”

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.

“…They reported the results for different nanoparticle-based nanofluids and found an improved heat-transfer rate. Azimi and Riazi [19] investigated the heat-transfer behavior in GO/H 2 O nanofluid between parallel disks. For mathematical treatment of the nanofluid model, they adopted a Galerkin-based homotopy analysis method and reported the results for the flow characteristics.…”

Thermal enhancement and irreversible phenomena in colloidal suspension (Al2O3-H2O) is a potential topic of interest from the aspects of industrial, mechanical and thermal engineering; heat exchangers; coolant car radiators; and bio-medical, chemical and civil engineering. In the light of these applications, a colloidal analysis of Al2O3-H2O was made. Therefore, a colloidal model is considered and treated numerically. The significant influences of multiple parameters on thermal enhancement, entropy generation and Bejan parameter are examined. From the presented colloidal model, it is explored that Al2O3-H2O is better for the applications of mechanical and applied thermal engineering. Moreover, fraction factor tiny particles are significant parameters which enhanced the thermal capability of the Al2O3-H2O suspension.

“…Choi and Eastman [7] were the first to propose the term nanofluid that represents the fluid in which nanoscale particles are suspended in the base fluid with low thermal conductivity such as water, ethylene glycol, and oil. In recent years, many researchers have studied and reported nanofluid technology experimentally or numerically in the presence of heat transfer [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. Ibrahim and Shankar [24] studied MHD nanofluid flow and heat transfer over a stretching sheet in the presence of thermal radiation and slip conditions.…”

Heat and mass transfer behavior of unsteady flow of squeezing nanofluids between two parallel plates in the sight of uniform magnetic field with slip velocity effect is investigated. The governing equations representing fluid flow have been transformed into nonlinear ordinary differential equations using similarity transformation. The equations thus obtained have been solved numerically using Runge-Kutta-Fehlberg method with shooting technique. Effects on the behavior of velocity, temperature, and concentration for various values of relevant parameters are illustrated graphically. The skin-friction coefficient and heat and mass transfer rate are also tabulated for various governing parameters. The results indicate that, for nanofluid flow, the rates of heat and mass transfer are inversely proportional to nanoparticle volume fraction and magnetic parameter. The rate of mass transfer increases with increasing values of Schmidt number and squeeze number.
