MHD flow of nanofluid over moving slender needle with nanoparticles aggregation and viscous dissipation effects

Abstract

The study of boundary layer flows over an irregularly shaped needle with small horizontal and vertical dimensions is popular among academics because it seems to have a lot of uses in fields as different as bioinformatics, medicine, engineering, and aerodynamics. With nanoparticle aggregation, magnetohydrodynamics, and viscous dissipation all playing a role in the flow and heat transmission of an axisymmetric [Formula: see text] nanofluid via a moving thin needle, this article provides guidance on how to employ a boundary layer for this purpose. In this case, we utilized the similarity transformation to change the dimensional partial differential equation into the dimensionless ordinary differential equation. We utilize MATHEMATICA to include shooting using RK-IV methods after identifying the numerical issue. Several characteristics were measured, leading to the discovery of a broad variety of values for things like skin friction coefficients, Nusselt numbers, velocity profiles, and temperature distributions. Velocity profile decreases with increasing values of [Formula: see text] and increases against [Formula: see text] Temperature profiles enhances with increasing values of [Formula: see text], and [Formula: see text] The reduction in skin friction between a needle and a fluid can be observed when the values of M and [Formula: see text] are boosted. Furthermore, it was also noticed an increase in heat transfer on needle surface dramatically when [Formula: see text], and M were raised, whereas [Formula: see text] displayed the opposite effect. The findings of the current study are compared with prior findings for a particular instance in order to confirm the findings. Excellent agreement between the two sets of results is found.

Numerical thermal study of ternary nanofluid influenced by thermal radiation towards convectively heated sinusoidal cylinder

“…Thus, the RKF-45 numerical scheme (see Refs. [ [40] , [41] , [42] , [43] , [44] , [45] ]) adopted for the solution and to investigate the impact of ingrained physical constraints. In this scheme, initial transformations essential to reduce the model into IVP (see Refs.…”

Numerical Simulations of Chemically Dissipative MHD Mixed Convective Non-Newtonian Nanofluid Stagnation Point Flow over an Inclined Stretching Sheet with Thermal Radiation Effects

“…Bakar et al, [32] looked at how a porous medium filled with a nanofluid, a permeable surface, magnetohydrodynamics (MHD), and internal heat production affected the flow of a mixed convection boundary layer the research by Rafique et al, [33] examines how heat is transferred by nanofluids floating in various-sized carbon nanotubes across a stretched surface. Ali et al, [34] investigated MHD flow of nanofluid over a moving thin needle with impacts of nanoparticle aggregation and viscous dissipation. Nanofluid flow over stretching/shrinking sheets has been studied by several researchers using a variety of theoretical approaches [35][36][37][38][39].…”
