Numerical results for influence the flow of MHD nanofluids on heat and mass transfer past a stretched surface

Abstract

Due to its significant applications in physics, chemistry, and engineering, some interest has been given in recent years to research the boundary layer flow of magnetohydrodynamic nanofluids. The numerical results were analyzed for temperature profile, concentration profile, reduced number of Nusselt and reduced number of Sherwood. It has also been shown that the magnetic field, the Eckert number, and the thermophoresis parameter boost the temperature field and raise the thermal boundary layer thickness while the Prandtl number reduces the temperature field at high values and lowers the thermal boundary layer thickness. However, if Lewis number is higher than the unit and the Eckert number increases, the concentration profiles decrease as well. Ultimately, the concentration profiles are reduced for the variance of the Brownian motion parameter and the Eckert number, where the thickness of the boundary layer for the mass friction feature is reduced.

Insights into Partial Slips and Temperature Jumps of a Nanofluid Flow over a Stretched or Shrinking Surface

“…The stability analysis [30][31][32] is also important, and new approaches to the analysis of temperature jump appeared in the literature [33]. In this computational study, the Chebyshev pseudospectral approach [19][20][21][22][23] with mathematical software code was used to investigate the relevance of partial slips and temperature jumps in terms of the heat and mass transfer of a boundary layer nanofluid flow over a stretched or shrinking surface. As a result, the numerical results can be interpreted according to Table 1, which shows how to apply the friction factor and Nusselt number to relevant physical factors [25].…”

“…Considering these factors and deriving inspiration from the previously mentioned works in the field of nanofluids, there is a physical reason to investigate the topic of the current article in order to attain improvements in the dimensionless aspects of the stream function, temperature, and volume of nanoparticles. As a result, the current work's goal is to debate the impact of the boundary conditions of partial slips and temperature jumps on nanofluid heat and mass transfer over a stretching or shrinking surface, and the physical model of nonlinear ordinary differential equations is numerically solved using the Chebyshev method of collocation [19][20][21][22][23]. The results of this study indicate that the thickness of the thermal barrier layer of the heat transfer rate rises as the temperature jump parameter increases, for both stretching and shrinking sheets, thereby reducing the heat transfer rate.…”

Nanoparticles (e.g., Copper (Cu), Silver (Ag), Alumina (Al2O3), Titanium (TiO2)) range from 1 to 100 nm in diameter defined by Oztop et al, [5].The base liquid's thermal conductivity is improved by (10% − 50%) if it is suspended by a low volumetric fraction (less than 5%) of nanoparticles are discussed by Eastman et al, [6][7][8]. In Khan et al, [9], the authors examined improvements in the thermal conductivity of fluids (such as oil, water, and ethylene glycol mixture) which are poor heat transfer by suspending nano /micro or large particle materials in these fluids.…”
