“…The nanofluid characteristics according to their properties must be known for all applications. Many studies are available in the literature understanding the fluid characteristics (Uddin et al, 1 Uddin & Rasel, 2 Saeed et al, 3 Prasad et al, 4 Falodun & Omowaye, 5 Buzuzi & Buzuzi, 6 Raju et al, 7 Gireesha et al, 8 and Alam et al 9 ). Idowu & Falodun 10 studied the effects of pertinent fluid parameters varying the viscous nature of the fluid along with the caloric conductance in a porous plate.…”

The nanotechnology‐based nanofluid has extraordinary prospects in heat transfer engineering. Analysis of these applied nanofluids can yield the appropriate combinations of various useful physical parameters. In the present study, the incompressible boundary layer flow of a nanofluid in the presence of the variable chemical reaction, temperature‐dependent viscosity, hydromagnetic force, and the radiation past an infinite vertical plate has been investigated. The governing nanofluid equations are simplified to ordinary differential equations, which are solved using the function bvp4c from MATLAB. The effects of the physical parameters including the similarity parameter, magnetic field, two dimensionless constant temperatures, Schmidt number, local Grashof number, radiation parameter, local chemical reaction parameter, kinematic diffusion parameter, and temperature‐independent kinematic diffusion parameter on the velocity, temperature, concentration and the local Nusselt number are demonstrated. The results show that as the magnetic field parameter increases, the heat transfer decreases, and the increase of the radiation parameter yields the opposite effect. The kinematic diffusion and the chemical reaction parameters greatly stimulate the concentration of nanofluid and reduce the heat transfer.

“…Beside this, Chen and Liu [6] dealed with heated cylinder submerged in a salt-stratified fluid and Kalla et al, [7] considered the case of shallow porous cavity with vertical fluxes of heat and mass in their study. Double diffusive convection in Newtonian fluid [8][9][10][11] and various types of non-Newtonian fluid [12][13][14][15][16][17][18][19][20][21][22] are reported with different conditions. These types of non-Newtonian include viscoelastic [12,17], power-law fluid [13,19], nanofluid [14,20], viscoelastic nanofluid [15], Maxwell fluid [16] and Casson fluid [18,[21][22].…”

The assisting boundary layer flow, heat and mass transfer have wide applications in engineering devices and in nature: for example, nuclear reactors, heat exchangers, solar receivers, atmospheric flow and lake circulation. Therefore, the numerical study of boundary layer flow, heat and mass transfer on Newtonian or non-Newtonian fluid has to be developed, as a reference to experimental works. Therefore, the mathematical modelling and numerical solutions of boundary layer flow, heat and mass transfer on magneto-hydrodynamics Casson fluid are reported in this paper. The model problem is subjected to the presence of mixed convection with assisting flow, together with the buoyant feature. The Casson fluid is assumed to flow over an exponentially stretching sheet, together with the exponential variations of fluid temperature and fluid concentration. The momentum, energy and concentration equations are formed as the controlling equations and written as partial differential equations (PDE). Subsequently, these equations were transformed into the ordinary differential equations (ODE) by using the similarity transformation. Finally, the ODE are solved numerically by bvp4c program in MATLAB software. The graphs of velocity, temperature and concentration profiles and the numerical values of skin friction coefficient, local Nusselt number and local Sherwood number are presented. These results are obtained due to the controlling parameter, namely as magnetic field, assisting flow and buoyancy ratio parameters. As a result, the increment and decrement of the velocity, temperature, concentration, skin friction coefficient, local Nusselt number and local Sherwood number are influenced by magnetic field, assisting flow and buoyancy ratio parameters.

“…The effects of velocity and thermal wall slip on magneto-hydrodynamics boundary layer viscous flow and heat transfer of a nanofluid over a non-linearly stretching sheet have been studied numerically by Dodda Ramya et al (2018). The effect of thermal diffusion (Soret) on unsteady magneto-hydrodynamic mixed convection flow through an accelerated vertical wavy plate embedded in a Darcian porous medium was examined by Prasad et al (2019). Kotnurkar and Giddaiah (2019) investigate the study of double-diffusive convection on peristaltic flow under the assumption of long wavelength and low Reynolds number.…”

Purpose This paper aims to report the investigation of over heat and mass transfer of convective Casson fluid flow over a moving vertical plate with nonlinear thermal radiation and convective boundary conditions. Design/methodology/approach The main partial differential equations of the flow, heat and concentration profiles were rehabilitated to nonlinear ordinary differential equations by using an appropriate similarity transformation. The resultant nonlinear ordinary differential equations (ODEs) are solved numerically applying fourth-order Runge–Kutta shooting technique and functions of ODE45 from MATLAB. Findings The effect of convective heat transfer, buoyancy ratio parameter, nonlinear thermal radiation, Prandtl number, Rayleigh number and Schmidt number over velocity, temperature and concentration profiles, equivalent to abundant somatic parameters were graphically scrutinized. Originality/value All the results are very promising and further there is got good agreement of results when compared with earlier published results at limiting conditions.
