“…The validation studies are carried out for laminar distilled water and 5% copper-water nanofluid flow in the straight channel. The numerical results are then compared with that of Santra et al [26], which include the inlet temperature of 293K, upper and lower wall preserve at uniform wall temperature condition, height of channel (0.01 mm), channel length and the diameter of nanoparticles (100 nm). The result shows a good agreement as shown in Figure 3.…”

The present investigation deals with the case of an Ag (CuO or Al2O3)-water nanofluid' convection phenomenon within a square enclosure, which including two heated sources, of a square shape. To do so, a computer code, based on the finite volume approach and the SIMPLER algorithm, is adopted to solve the general coupled equations. By studding the impact of some pertinent parameters such the Rayleigh number, the heaters' vertical location within the enclosure, as well as the nanoparticles' volume fraction and its type on the nanofluid flow and heat behaviors, the numerical predictions proved the nanoparticles type is the key factor for the heat transfer enhancement within such industrial geometry, side by side with the increasing function of the Rayleigh number and the nanoparticles' volume fraction. Unlike the latter, the increase in the heaters' vertical location within the enclosure affects the nanofluid flow, but it has no significant impact on the mean transfer rate.

“…Eastman et al [12] showed that adding 5% nano-crystalline copper oxide particles into water increases thermal conductivity of water approximately 60%. Santra et al [13] studied heat transfer in two dimensional horizontal duct for a Reynolds number ranging from 5 to 1500 and nanoparticle volume fraction from 0 to 0.05. It is indicated that heat transfer increases with increase in Reynolds number and nanoparticle volume fraction.…”

ABSTRACT:In this study, effects of water-based Al2O3 nanofluids on flow characterictisc and heat transfer enhancement in rectangular corrugated channels are investigated numerically. Flow between two isothermally walls is assumed to be two-dimensional, fully developed and laminar. Phase angle effects were investigated with varying the phase angle from 180 to 0 while keeping the corrugated wall geometries fixed. Governing, momentum and energy equations are numerically solved using finite volume method based on SIMPLE algorithm. Simulations are performed for nanoparticle volume fractions between 0 to 0.08 and Reynolds number ranging from 500 to 2000. Numerical results are compared with results obtained from literature and they are in close agreement with each other. Effects of phase angle, nanoparticle volume fraction and Reynolds number on Nusselt number, friction factor and thermal performance factor are investigated.
