“…One of the main conclusions of the investigation was that sphereshaped nanoparticles reached the lowest temperature, whereas lamina-shaped 𝑆𝑖𝑂 2 and 𝑀𝑜𝑆 2 -𝑆𝑖𝑂 2 nanoparticles reached the highest temperature. The goal of the current study [22] was to ascertain the influence of particle shapes and radiation parameters. The lamina shape of cu-ethylene glycol is superior than other types.…”

This article presents a numerical investigation of thin film flow and heat transfer for lamina, tetrahedron, and hexahedron-shaped nanomaterials of Fe3 O4 and Al2 O3 over a time-dependent radially vertical stretching surface. Moreover, the magnetohydrodynamics and viscous dissipation effects are also incorporated. A similarity transformation is employed to produce the nonlinear governing system of equations, which is numerically solved using the BVP4C method in MATLAB. The study shows that film thickness depends on the unsteadiness parameter, with an increase in the parameter causing decrease in film thickness (β), velocity, and temperature. The lamina and hexahedron shapes provide maximum and minimum film thickness for Fe3 O4 and Al2 O3 both nanoparticles, while the hexahedron and lamina shapes generate maximum and minimum skin friction. The Nusselt numbers exhibit the opposite effect. These findings provide insights into thin film flow's fundamental mechanisms and applications.

The objective of the current analysis is to study the influence of MHD on flow of an ethylene glycol-based nanofluid containing copper nanoparticles through a exponential stretching sheet. Several parameters including Dufour, thermal radiation, Magnetohydrodynamic (MHD), and Eckart number, were investigated for their impacts on fluid flow, heat and mass transfer profiles, and thermal convective boundary conditions, while Navier velocity slip was also considered. The basic PDEs are transformed into nondimensional ODEs using appropriate transformations and numerically characterized by bvp4c. The graphs examine the influence of relevant parameters on heat and mass transfer profiles. The velocity profile decrease with slip effect. As the Biot number increased, the thermal layer became thicker. The Nusselt number are the decline functions of magnetic field, Eckert number and Brownian diffusion but the local Sherwood number enhanced with these parameters. The Nusselt number intensifies with radiation parameter Rd, slip parameter \(\lambda\) and Biot numberBi. The temperature and concentration profiles rises with increase in Nt.

Influence of the nanoparticles and uniform magnetic field on the slip blood flows in arterial vessels

et al. 2019

View full text Add to dashboard Cite

The present study investigates the combined influence of the nanoparticles and uniform magnetic field applied on the slip blood flow. Blood conveyed through the hollow arterial tube is described as a third-grade non-Newtonian fluid with time dependent viscosity and formulated by the second-order nonlinear ordinary differential equations. Therefore, the regular perturbation method as an approximate analytical method can be applied providing a solution to the coupled system of equations. The results obtained from the solution are used to show the effect of parameters including the magnetic parameter, the viscous dissipation and the pressure gradient on the slip blood flow. Analytical results reveal augmentation of the pressure gradient and the magnetic parameter decrease the velocity value whilst the viscous dissipation augmentation increases the temperature. Also, the comparison between the analytical results with the results obtained from numerical solution shows the good agreement.
