“…They found that in the case of increased radiation, a CuO-based nanofluid behaved much better than a Al 2 O 3 -based nanofluid. Gangadhar et al (2021) investigated the flow of a radiative EMHD fluid on a Riga plate due to heat convection using the modified Buongiorno model. Rahman et al (2022) examined the effects of suction and magnetic factors on a nanofluid flow containing copper oxide, metal, alumina, and titanium dioxide nanoparticles over a spinning disc.…”

The suspension of nanoparticles in base liquids has found extensive applications in various industrial processes like nanomedicines, microsystem cooling, and energy conversion. Owing to its important applications, this article investigates the hybrid nanofluid flow over a three-dimensional stretching surface. The fluid is influenced by thermal radiation, chemical reaction, and a variable thermal source/sink. The set of equations that administer the fluid behavior has been transformed to dimensionless form by a suitable set of similarity transformations that are further solved by the homotopy analysis method. It was found that as the ratio parameter increased, the velocity of hybrid nanofluid velocity decreased along the primary direction and increased along the secondary direction. The temperature characteristic was augmented with greater values of nonlinear thermal radiation and source/sink factors. Growth in the chemically reactive factor and Schmidt number has an adverse effect on the concentration profile of the hybrid nanofluid flow. A comparative analysis of the current results and those established in the literature was conducted. A close agreement with those published results was found. It was noted that temperature and concentration increase more quickly for the MoS2+MgO/H2O hybrid nanofluid than the MoS2/H2O,MgO/H2O nanofluids.

“…Gangadhar et al 34 discused the convective heat transfer characteristics of a hybrid nanofluid mixture with slip effects by considering Tiwari-Das nanofluid modeland and he concluded that increased slip effects greatly enhance the local heat transfer rate in the nodal and saddle point regions. Some very recent related studies can be found in [35][36][37][38][39][40][41][42][43][44] . Sharma et al 45 discussed the transfer of heat over a porous rotating disk and concluded that with the increase in the magnetic field, viscous dissipation, and the thermal radiation mechanism, the magnitude of the magnetic-fluid temperature is also increased.…”

Flow towards a rotating disk is of highly practical significance in numerous engineering applications such as Turbine disks, rotary type machine systems and many more. In light of this, the current work is an attempt to explore MHD oblique flow towards a rotating disk. Hydromagnetic effects in addition to heat transfer is taken into consideration. The flow governing Partial Differential Equations are altered to a system to coupled non-linear Ordinary Differential Equations through scaling group of transformations which afterwards are tackled using Shooting Algorithm. The impact of obliqueness parameter γ, rotation ratio parameter $$\alpha$$ α and magnetic field parameter M on 2-dimensional and 3-dimensional stream contours are presented. Location of the shear center varies with magnetic field parameter. Heat flow at the disk surface boosts with magnet field parameter M and rotation ratio parameter $$\alpha$$ α .

“…The nanoparticles are suspended in the second-grade fluid to get around this restriction. Many researchers have recently utilised the flow of second-grade nanofluid over Riga plate [3,4], exponentially stretched surfaces [5,6], stretched cylinders [7] and stretched surfaces [8][9][10] under a variety of physical conditions, including nonlinear thermal radiation, activation energy, mixed convection, magnetic fields, slip boundary conditions, Soret and Dufour effects, homogeneous-heterogeneous reactions, and many more [11][12][13][14].…”

Modern challenges include improving heat transmission in a range of industries, including electronics, heat exchangers, bio and chemical reactors, etc. Innovative heat transfer fluids like nanofluids have the potential to increase energy transport effectively. This gain is attained as a result of improved effective thermal conductivity and modified fluid flow dynamics. Therefore, the topic of this paper is improving heat transmission using nanofluids. The objective is to deal with the second grade fluid model passing through a horizontal circular cylinder with mixed convection and suspended nanoparticles. The respective nanoparticles and based fluid of Copper (Cu) and carboxymethyl cellulose (CMC-water) are considered. Both non-dimensional and non-similarity transformation variables are utilized to convert the governing equations to a system of partial differential equations (PDEs). Reduction to ordinary differential equations (ODEs) is attained from the resulting PDEs at the lower stagnation area and then tackled via the Runge-Kutta Fehlberg technique (RKF45) in the Maple software. Graphs are used to illustrate the detailed description of the results of dimensionless parameters like the Biot number, mixed convection, and the second grade parameter. Results show that the fluid slows down while the temperature increases as the value of second grade parameter rises.
