Double Slip Effects and Heat Transfer Characteristics for Channel Transport of Engine Oil With Titanium and Aluminum Alloy Nanoparticles: A Fractional Study

Abstract

The core purpose of this study is the formulation of a fractional model to anticipate the improvement in heat transfer potential of a particular diathermal oil i.e. engine oil under thermal radiative flux. The magnetohydrodynamic (MHD) freely convectional transport of two different types of engine oil based nanofluids comprised of Titanium (Ti 6 Al 4 V) and Aluminum (AA7075) alloy nanoparticles is considered in a vertical channel frame. In addition, the channel is assumed to be embedded in a permeable media and slip effects are observed at both ends. The transmutation of the governed model from classical to fractional environment is achieved by operating the Atangana-Baleanu derivative. To procure solutions of the proposed fractional model, Laplace transform is employed with an adequate choice of some unit-free quantities. Numerical simulations are performed and outcomes are conveyed through graphical illustrations to discuss the contribution of considered alloy nanoparticles in flow mechanism and thermal behavior of engine oil. It is reported that Ti 6 Al 4 V is more effective to enhance the thermal efficiency of engine oil as compared to AA7075. It is claimed that there is an augmentation of 32.50% in the heat transfer rate of engine oil due to Ti 6 Al 4 V, which is almost twice the improvement in heat transfer rate provided by AA7075. Furthermore, the slip parameters lead to expedite the channel flow of engine oil. This study culminates that Ti 6 Al 4 V and AA7075 significantly improve the lubrication and cooling characteristics of engine oil.

Finite element analysis on the hydrothermal pattern of radiative natural convective nanofluid flow inside a square enclosure having nonuniform heated walls

“…Related studies are in References. [59][60][61][62][63] Therefore, it is perceived that a substantial number of studies have been completed to show the hydrothermal pattern of nanofluids or simple Newtonian liquid flow within a square chamber with bottom and top surfaces that are differentially heated. However, no such corresponding report or investigation is available for magnetized radiative ferrofluid flow when the lowermost and sidewall of the square chamber are both uniformly or nonuniformly heated, despite having several real applications as declared earlier.…”

Toward the heat convection enhancement of nanofluids flowing in a 3D microchannel affected by a nonuniform magnetic field

“…Anwar et al 26 looked at a Brinkman‐type ferrofluid in similar work. The heat transfer performance of an engine oil‐based nanofluid flowing through a vertical channel was investigated by Asifa et al 27 Titanium nanoparticles have been shown to be more effective than aluminum alloy nanoparticles in improving engine oil heat transfer. Other related studies, such as in References [28, 29] can be found in the literature.…”
