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.

The nanofluids became much of interest due to their superior heat mechanism over the conventional fluids. The addition of nanoparticles in the host solvent enhances the internal ability of the liquid to store and transmit heat. Therefore, these fluids are widely used in biomedical engineering, detergents, medication, applied thermal engineering, mechanical, and chemical engineering and so forth. Keeping in mind the significance of nanofluids, this study is conducted to investigate the comparative heat transmission in and under the Effective Prandtl Number Model (EPNM) effects over a vertical permeable cylinder. Formulation of the model is carried out over a vertical cylinder about the stagnation point and the heat transport model is achieved after the successful implementation of the cylindrical stream function, nanofluids effective characteristics, and cylindrical similarity equations. The mathematical treatment was done via RK technique and furnished the results. The nanofluids have the capacity to control the fluid motion more effectively than ordinary fluid and combined convection is better where rapid fluid movement is desired. In the existence of EPNM, higher heat transmission is achieved and is prominent for based on their thermophysical values. Further, the skin friction and Nusselt number are optimum for against .

The study of advanced nanofluids termed as Tetra nanofluid is of potential interest now a days. These fluids are upgraded generation of conventional nano to ternary hybrid nanofluids with outstanding characteristics. Applications of this class frequently occur in applied thermal engineering, nano‐lubrication, chemo‐therapy, chemical engineering, oil paint industry, coolant of nuclear plant and many other applied research areas. This study concerns with the development of innovative thermophysical rules for Tetra Hybrid nanofluid and their utilization in advanced heat transfer model. The governing laws updated through addition of thermal condition, dissipation effects, thermal radiations and upgraded nanofluid properties. Finally, the Blasius and Sakiadis model achieved and analyzed the heat transfer trends through numerical technique. Keen analysis of the drawn results show that Blasius model has much ability to transfer the heat than Sakiadis model. Induction of thermal radiations, dissipation effects and thermal convective condition is like a catalysis in the study of advanced tetra nanofluid model and boosts the temperature.
