“…Hayat et al [6] have discussed the chemically reactive flow of third grade fluid by an exponentially convected stretching sheet. Mushtaq et al [7] have introduced a numerical study for rotating flow of nanofluids caused by an exponentially stretching sheet. Nanofluid was first introduced by Choi [8] to describe the case of a fluid with suspended nanoparticles.…”

The effect of magnetic field on the three-dimensional flow of a nanofluid induced by exponentially stretching surface is studied. The fluid temperature is also assumed to be distributed exponentially. The problem is solved using two methods: The first one is numerical and the second is homotopy analysis method (HAM). The obtained results are compared with some previous studies in some limiting cases and found to be in a good agreement. The results reveal the roles that the nano-particle volume fraction and magnetic field strength play in the variation of both of the fluid temperature and velocity.

Research on optimization of entropy generation in nanofluid flow gained much interest. In this study, the Walter's-B nanofluid flow is considered to analyze the irreversibility in cubic autocatalysis. Fluid motion is considered in presence of viscous dissipation, magnetohydrodynamics (MHD), radiation, and heat generation absorption. Homotopy analysis method (HAM) is employed to solve nonlinear ordinary differential system. Results show that fluid flow reduces for larger Weissenberg and Hartman numbers. Temperature gradually enhances for larger Weissenberg number and radiation parameter. For higher estimation of thermophoresis parameter, the temperature and concentration are enhanced. Opposite impact of Hartman and Weissenberg numbers is noticed for entropy generation and Bejan number. Disorderedness and Bejan number are reduced near the sheet, while the opposite trend is seen away from the sheet.

“…Moreover, increase in an average Nusselt number as increases in the cylinder size of the mixed convection case for various Richardson number was observed [12]. Furthermore, the nanoparticle volume fraction [13]- [16], cylinder rotation speed [16]- [18] and the Reynolds number [17]- [19] were found significantly influenced the heat transfer rate of rotating cylinder. In spite of the enhancement in the heat transfer rate, increases in the thickness of thermal boundary layer was also observed as the effect of the increment in the nanoparticle volume/weight fraction for infinite single rotating tube [19]- [21].…”

Study on the heat transfer of TiO2/water nanofluid flows inside annulus of the finite rotating cylinders was done numerically. Inner shaft and outer tube were rotated in co-rotating and counter-rotating direction. The k-epsilon turbulent model and the Mixture-multiphase model were used to treats the turbulence flow and the multiphase flows of the TiO2/water nanofluid, respectively. Results of the current work are in agreement with published work. Results showed that increased in Reynolds number the Nusselt number increases. The distribution of the Nusselt number at the specific location along the heated inner shaft for co-rotating and counter-rotating cases shows a different distribution profile. The counter-rotating case was found to be more efficient in enhancing the heat transfer rate in comparison to the co-rotating case. This observation is suggested because of the boundary layers disturbances that originate from the additional vortices produced by the competing rotational speed between inner shaft and outer tube.
