“…With this understanding, a number of investigations have been conducted to outline the boundary layer flow of nanofluids with heat and mass transfer phenomena. For instance, the recent studies of Haile and Awgichew [3] revealed that the increase in hydrodynamic slip reduces the velocity of the nanofluid; but it enhances the temperature and nanoparticle volume fraction. Some other studies on boundary layer flow of nanofluids are also indicated in the cited articles [4,5,6,7,8,9,10].…”

In this study, a convective heat and mass transfer phenomena in a time-dependent boundary layer flow of tangent hyperbolic nanofluid over a permeable stretching wedge has been examined with respect to some pertinent thermo-physical parameters. Convenient similarity transformation is used to reformulate the dimensional partial differential equations into dimensionless system of ordinary differential equations. The reduced set of equations is solved by the homotopy analysis method implemented in Mathematica environment. The effects of the relevant parameters on velocity, temperature and concentration profiles were examined in detail. The impacts of the parameters on the rates of momentum, heat and mass transfer are also analyzed quantitatively in terms of the wall friction coefficient, local Nusselt number and Sherwood number, respectively. Analysis of the results reveals that the increase in the buoyancy ratio parameter facilitates the flow velocity and the increase in the dissipation parameter maximizes the temperature distribution and nanoparticle concentration near the surface of the wedge. Moreover, the analytic approximations obtained by implementing the homotopy analysis method are found in excellent agreement with some previously published results.

“…On the other hand, the retardation of the flow due to an applied magnetic field can also dissipate heat, which is known as Ohmic dissipation or Joule heating. Some of the recent studies on thermal radiation, heat source, and dissipation effects are indicated in Haile and Awgichew 12 and Ibrahim and Negera. 13 To enhance the working efficiency of manufacturing industries, further understanding on the flow and transport phenomena of electrically conducting fluids is very essential to efficiently design, operate, and regulate modern-day flow systems.…”

This paper presents the analytical study of heat and mass transfer in a two-dimensional time-dependent flow of Williamson nanofluid near a permeable stretching sheet by considering the effects of external magnetic field, viscous dissipation, Joule heating, thermal radiation, heat source, and chemical reaction. Suitable transformations are introduced to reformulate the governing equations and the boundary conditions convenient for computation. The resulting sets of nonlinear differential equations are then solved by the homotopy analysis method. The study on the effects of relevant parameters on fluid velocity, temperature, and concentration profiles is analyzed and presented in graphical and tabular forms. Upon comparison of the present study with respect to some other previous studies, a very good agreement is obtained. The study points out that the transfer of heat can substantially be enhanced by decreasing viscoelasticity of the fluid and the transfer of mass can be facilitated by increasing permeability of the stretching sheet.

“…Since then, nanofluids become the working fluids in a number of industrial and biomedical applications such as microelectronics, fuel cells, spray coating, pharmaceutical procedures, and many other advanced cooling and thermal management systems. Some of the recent studies on nanofluid flow characteristics are presented in various studies 5–8 . Recently Samantaray et al 9 have studied Darcy–Forchheimer up/downflow of entropy optimized radiative nanofluids with second‐order slip, nonuniform source/sink, and shape effects.…”

This article investigates the radiation and chemical reaction effects on the free convection heat and mass transfer flow of Casson nanofluids (Cu and TiO2) over an inclined porous vertical plate embedded in a porous medium in the presence of radiation absorption and constant heat source under fluctuating boundary conditions. The plate is moved with a constant velocity of U0, and temperature and the concentration are assumed to be fluctuating with time harmonically from a constant mean at the plate. The perturbation technique is applied to solve the governing equations of the flow and pointed out the variations in velocity, temperature, and concentration with the use of graphical presentations. The impact of several parameters on local skin friction, Nusselt number, and Sherwood number is also noticed and discussed. It is concluded that the resultant velocity reduces with increasing Casson parameter and suction parameter, velocity, and temperature enhanced with increasing radiation absorption and diffusion thermo parameters. Also, it is noticed that the solutal boundary layer thickness decreases with an increase in chemical reaction parameters. It is because chemical molecular diffusivity reduces for higher values of Kr.
