“…Akbari 39 measured via way of means of viscosity of ethylene glycol/MgO-MWCNT hybrid nanofluid at quantity ratios of nanoparticles starting from zero to 1% inside a temperature variety of 30 to 60° C. The CNT / Fe 3 O 4 nanoparticles in nanofluid are used as a cooler in a small channel temperature changer, and its houses are numerically tested. Waqas et al 40 explored the effect of thermal radiation in hybrid nanofluid for Powell-Erying model. The heat transfer enhancement in the mixed convection flow of hybrid nanofluid with temperature jump was reported by Khalid et al 41 .…”

The formation of entropy in a mixed convection Casson nanofluid model with Arhenius activation energy is examined in this paper using magnetohydrodynamics (MHD). The expanding sheet, whose function of sheet velocity is nonlinear, confines the Casson nanofluid. The final equations, which are obtained from the first mathematical formulations, are solved using the MATLAB built-in solver bvp4c. Utilizing similarity conversion, ODEs are converted in their ultimate form. A number of graphs and tabulations are also provided to show the effects of important flow parameters on the results distribution. Slip parameter was shown to increase fluid temperature and decrease entropy formation. On the production of entropy, the Brinkman number and concentration gradient have opposing effects. In the presence of nanoparticles, the Eckert number effect's augmentation of fluid temperature is more significant. Furthermore, a satisfactory agreement is reached when the findings of the current study are compared to those of studies that have been published in the past.

“…On their interest study of MHD hybrid Cu–Al 2 O 3 /H 2 O nanofluid flow past a permeable stretching sheet by Wahid et al (2020), it was stated that the reduced Nusselt number increases as the Cu-nanoparticle volume fraction is escalated. There are several papers on HNFs available in the literature reviewing; for example, see Sarkar et al (2015), Sidik et al (2016), Sundar et al (2017) and Eshgarf et al (2021) and in the recently published papers related to the boundary layer in Aly and Pop (2019), Waini et al (2019, 2020), Aly and Ebaid (2021), Balaji et al (2021), Aly et al (2021), Sepehrnia et al (2022), Usafzai et al (2022), Usafzai and Aly (2022), Xuan et al (2022), Waqas et al (2022), Khashi’ie et al (2022), Roşca et al (2022), Roy and Pop (2022), Said et al (2022), Aly et al (2023) and also in the four interested books by Das et al (2007), Shenoy et al (2016), Nield and Bejan (2017) and finally Merkin et al (2022).…”

Purpose This paper aims to study the magnetohydrodynamic (MHD) wall jet of a hybrid nanofluid flow over a moving surface with a thermally convective surface, wall moving with suction/injection. Design/methodology/approach On using appropriate similarity transformations, the governing equations that describe the model are converted into a system of nonlinear ordinary differential equations. These equations are solved both analytically and numerically using standard two-point boundary-value problem solvers and Chebyshev pseudospectral differentiation matrix method, respectively. Findings These results show that the HNF is heating/cooling with growth of the positive/negative values of the parameter measuring the velocity of the moving surface. The temperature distributions increase, where the thermal boundary layer gets thicker, as the magnetic field strengthens and with an increase in the absolute value of the Biot number. Originality/value The current findings for the HNFs are new and original. They generalize successfully the problems investigated previously by different researchers for the cases of fluids and also nanofluids.

“…Heat exchanger thermohydraulic performance increases heat transfer coefficients and lowers working fluid resistance. Some heat transfer enhancement techniques have been developed, including turbulence promoters 2 – 11 and nanofluids 12 – 15 . Due to its simplicity of maintenance and low cost, twisted tape insertion is one of the most successful ways of enhancing heat transfer in a heat exchanger 7 , 16 .…”

Covalent and non-covalent nanofluids were tested inside a circular tube fitted with twisted tape inserts with 45° and 90° helix angles. Reynolds number was 7000 ≤ Re ≤ 17,000, and thermophysical properties were assessed at 308 K. The physical model was solved numerically via a two-equation eddy-viscosity model (SST k-omega turbulence). GNPs-SDBS@DW and GNPs-COOH@DW nanofluids with concentrations (0.025 wt.%, 0.05 wt.% and 0.1 wt.%) were considered in this study. The twisted pipes' walls were heated under a constant temperature of 330 K. The current study considered six parameters: outlet temperature, heat transfer coefficient, average Nusselt number, friction factor, pressure loss, and performance evaluation criterion. In both cases (45° and 90° helix angles), GNPs-SDBS@DW nanofluids presented higher thermohydraulic performance than GNPs-COOH@DW and increased by increasing the mass fractions such as 1.17 for 0.025 wt.%, 1.19 for 0.05 wt.% and 1.26 for 0.1 wt.%. Meanwhile, in both cases (45° and 90° helix angles), the value of thermohydraulic performance using GNPs-COOH@DW was 1.02 for 0.025 wt.%, 1.05 for 0.05 wt.% and 1.02 for 0.1 wt.%.
