“…They also computed and examined the effects of different parameters on the velocity, temperature, skin friction coefficient, and Nusselt number of nanofluid flow. Other works of nanofluids flow and heat transfer analysis can be found in [1,10,13,15,17,26,28].…”

In this paper, hydro-thermally performance of a circular concentric heat pipe is evaluated using the analytical least square method (LSM) and the accuracy of results is examined by fourth order Runge-kutta numerical method. In described problem, the pipe walls are permitted to carry different and opposite slip velocities of nanouids and they are either preserved at constant heat flux of outer wall with the inner wall insulated or vice versa. For this study, five distinct types of nanoparticles: Ag, Cu, Cuo, Al 2 O 3 and T iO 2 are considered in the water base fluid and the results of velocity profiles and Nusselt numbers in different slip conditions were presented and discussed. As a main result, by decreasing the distance between the pipes, more heat will transfer to nanofluids from the wall under the heat flux, so it makes larger Nusselt number.

“…Nowadays, nanofluids are the most important topics for the researchers due to their high application in industry and technology for facility of many phenomena such as heat transfer [1][2][3][4][5]. Based on Aziz [6] study, Dogonchi et al [7], Domairry and Aziz [8] and Domairry and Hatami [9] applied the mathematical methods for solving the mechanical engineering problems such as nanoparticles or particles motion modeling.…”

In this paper, Differential Transformation Method (DTM) is applied on governing equations of heat and fluid flow for a nanofluid over a horizontal flat plate. After obtaining the governing equations and solving them by DTM, the accuracy of results is examined by fourth order Runge-kutta numerical method. Due to infinite boundary condition for the stretching plate, outcomes need to an improvement method to be converged. For this aim, Padé approximation is applied on the obtained results which [10,10] Padé order had the best accuracy compared to numerical method. The influence of relevant parameters such as the transpiration parameter on temperature and nanoparticle concentration profile is discussed and it is concluded that by increasing this parameter, nanoparticles concentration over the plate decrease due to more fluid penetration from pores and this is the main reason of lower thermal boundary layer caused by fewer nanoparticles over the plate.

“…They found that the smallest particles have a more pronounced influence on the heat transfer behavior along the heat pipe. The flow and heat transfer characteristics of a nanofluid within a thin film over an unsteady stretching surface was performed by Ahmadi et al (2014). Their results revealed that the heat transfer rate is an increasing function of the solid volume fraction of the nanofluid whereas the opposite trend is observed for the friction factor.…”

The influences of thermal radiation and non -uniform heat source/sink in Falkner-Skan flow and heat transfer characteristics of nanofluids have been investigated. Three different types of nanoparticles, namely Copper, Cu, Alumina 2 3Al O , and Titania 2 TiO are considered by using water-based fluid with Prandtl number Pr = 6.2. The partial differential equations are transformed into the system of ordinary differential equations by applying similarity transformations which is then solved numerically. The result revealed that utilizing Cu-water nanofluid enhanced the heat transfer rate in comparison with 2 3Al O -water and 2 TiO -water nanofluids. The heat transfer rate is significantly boosted with an increase in the radiation parameter. Further, the opposite trend is observed with an increase in source/sink parameters and Eckert number.
