“…Their results found that the model could effectively capture several characteristics of the scaling process. Mohammadpour et al [35] combined the single-phase model (SPM) with Eulerian-Lagrangian (DPM) model to analyze the flow and heat transfer characteristics of a new type of microchannel and nanofluid synthetic jet device. Their output indicated that SPM over-predicted the heat transfer enhancement, while DPM realistically took into account the forces on the particles and the base fluid.…”

“…Consequently, the thermal conductivity is decreased for larger diameter of nanoparticles. Mohammadpour et al, [44] has performed a numerical study to investigate the effect of suspension of alumina particle with different diameter sizes in microchannel [44]. The diameter sizes of alumina particle that are chosen for the study are 50 nm, 75 nm, and 100 nm.…”

Nanofluid is a new class of heat transfer fluid that is introduced to enhance the heat transfer performance in various heat exchanging systems. Prior to invention of nanofluid, water is the most common fluid used to extract heat generated from the systems. The application of water has reached thermal bottleneck since it can only enhance the heat transfer performance up to a certain extent. The suspension of nanoparticles with enhanced thermal conductivity provides augmentation in heat transfer performance. Since then, nanofluids have received great interest from scientists and researchers due to significant higher thermal conductivity. Due to enhanced thermophysical properties, nanofluids can be incorporated into high heat transfer device such as solar thermal conversion system, heat exchanger, and electronic equipment. Understanding the factors that influence the heat transfer performance is extremely important for appropriate selection and implementation of nanofluids. The influence of nanoparticles material, nanoparticles size, nanoparticles concentration, nanoparticles shape and surfactant are reviewed systematically to provide a comprehensive understanding of nanofluids. The review aims to extensively discuss the application of nanofluids in engineering application such as microchannel heat sink (MCHS). Finally, the review aims to update the readers about the current progress of nanofluids along with challenges of nanofluids in engineering field.

Purpose This paper aims to investigate the effects of different volume fractions of Al2O3-water nanofluid on flow and heat transfer under chaotic convection conditions in an L-shaped channel, comparing the difference of numerical simulation results between single-phase and Eulerian–Lagrangian models. Design/methodology/approach The correctness and accuracy of the two calculation models were verified by comparing with the experimental values in literature. An experimental model of the L-shaped channel was processed, and the laser Doppler velocimeter was used to measure the velocities of special positions in the channel. The simulated values were compared with the experimental results, and the correctness and accuracy of the simulation method were verified. Findings The calculated results using the two models are basically consistent. Under the condition of Reynolds number is 500, when the volume fractions of nanofluid range from 1% to 4%, the heat transfer coefficients simulated by single-phase model are 1.49%–25.80% higher than that of pure water, and simulated by Eulerian–Lagrangian model are 3.19%–27.48% higher than that of pure water. Meanwhile, the friction coefficients are barely affected. Besides, there are obvious secondary flow caused by lateral oscillations on the cross sections, and the appearance of secondary flow makes the temperature distributions uniform on the cross section and takes more heat away, thus the heat transfer performance is enhanced. Originality/value The originality of this work is to reveal the differences between single-phase and two-phase numerical simulations under different flow states. The combination of chaotic convection and nanofluid indicates the direction for further improving the heat transfer threshold.
