“…Sahoo et al 10 studied the augmentation of thermal performance utilizing the 50:50 volume ratio of different nanoparticles in water‐based Al 2 O 3 in combination with Cu, Ag, TiO 2 , and Fe 2 O 3 hybrid nanofluid as a coolant for a louvered fin vehicle radiator theoretically. Among these, alumina and silver/water hybrid nanofluid suggests effectiveness and heat transfer rate of 0.8% and 3%, respectively, for a concentration of 1% and temperature of 80°C.…”

The effect of temperature and concentration on the thermophysical properties of fly ash-copper (80% fly ash and 20% Cu by volume) water-based stable hybrid nanofluid is studied. The experiments are conducted for the volume concentration range of 0 to 0.5% in the temperature range of 30 to 60°C. The nanoparticles have been characterized by transmission electron microscopy and dynamic light scattering to determine an average nanoparticle diameter of 15 nm. The stability of nanofluid in the presence of surfactant Triton X-100 is examined with the help of zeta potential. The maximum enhancement in thermal conductivity and viscosity is 19% and 22%, respectively. The outcome of the present study showed that density, thermal conductivity, and viscosity of the hybrid nanofluid increased, whereas specific heat decreased with an increase in the nanofluid concentration. In addition, the specific heat and thermal conductivity increase, there is a decrease in density and viscosity of the hybrid nanofluid with an increase in temperature.

“…According to Sahoo et al [11], when hybrid nano uids were used as a radiator coolant, Al 2 O 3 + Ag/water-based hybrid nano uid showed greater e ciency in numerical terms. In the presence of the magnetic eld, Anjali Devi and Surya Uma Devi [12] concluded that hybrid nano uid (Cu-Al 2 O 3 /water) showed a higher heat transfer rate.…”

Over the past decade, the preparation, characterization, and modeling of nano uids have been plentifully studied to improve the e ects of heat transfer. Hence, to gratify the advancements, this paper focuses on heat transfer e ects of three distinct hybrid nanoparticles (Al 2 O 3 {SiO 2 , Al 2 O 3 {TiO 2 , TiO 2 {SiO 2 ) with a base uid (water). Therefore, this work numerically investigated the e ect over a permeable at surface with an aligned magnetic eld in the presence of suction, injection, or impermeability together with the Marangoni convection of di erent hybrid nano uids. The present results were validated in accordance with previous experimental and numerical results. The e ects of solid volume fraction of hybrid nanoparticles, angle of inclination, magnetic parameter, and wall mass transfer parameter were studied and shown through graphs together with the surface velocity. In addition, the rate of heat transfer was presented in the tabular form. It was found that the rate of heat transfer increased as the wall mass transfer increased, considering the opposite e ect of the rise of magnetic parameter. Among the three hybrid nano uids, Al 2 O 3 {SiO 2 /water hybrid nano uid showed a higher surface velocity, Al 2 O 3 { TiO2/water hybrid nano uid had higher temperature pro le, and TiO2{SiO2/water hybrid nano uid exhibited a higher heat transfer rate.

“…By virtue of their complementary thermophysical properties, hybrid nanofluids (i.e. nanofluids with multiple nanoparticle materials and/or geometries) were employed in forced convection heat transfer applications such as minichannel heat sinks (Kumar & Sarkar 2018), plate heat exchangers (Bhattad, Sarkar & Ghosh 2018 a ), corrugated plate evaporators (Bhattad, Sarkar & Ghosh 2018 b ), louvered fin automobile radiators (Sahoo, Ghosh & Sarkar 2017), shell-and-tube condensers (Singh & Sarkar 2018), milk chilling (Bhattad, Sarkar & Ghosh 2018 c ) and solar thermal collectors (Sarkar, Ghosh & Adil 2015).…”

Numerical investigation of nanofluid particle migration and convective heat transfer in microchannels using an Eulerian–Lagrangian approach

et al. 2019

An Eulerian–Lagrangian modelling approach was employed in order to investigate the flow field, heat transfer and particle distribution in nanofluid flow in a parallel-plate microchannel, with a focus on relatively low Reynolds numbers ($Re\leqslant 100$). Momentum and thermal interactions between fluid and particle phases were accounted for using a transient two-way coupling algorithm implemented within an in-house code that tracked the simultaneous evolution of the carrier and particulate phases while considering timescale differences between the two phases. The inaccuracy of assuming a homogeneous particle distribution in modelling nanofluid flow in microchannels was established. In particular, shear rate and thermophoresis were found to play a key role in the lateral migration of nanoparticles and in the formation of particle depletion and accumulation regions in the vicinity of the channel walls. At low Reynolds numbers, nanoparticle distribution near the walls was observed to gradually flatten in the streamwise direction. On the other hand, for relatively higher Reynolds numbers, higher particle non-uniformities were observed in the vicinity of the channel walls. Furthermore, it was established that convective heat transfer between channel walls and the bulk fluid can either improve or deteriorate with the addition of nanoparticles, depending on whether the flow exceeded a critical Reynolds number of enhancement. It was also established that Brownian motion and thermophoresis had a major role in nanoparticle deposition on the channel walls. In particular, Brownian motion was the main deposition mechanism for nano-sized particles, whereas due to thermophoresis, nanoparticles were repelled away from channel walls. The result of the competition between the two is that deposition gradually increased along the streamwise direction.
