“…The grid refinement tests were conducted for different values of Ra (10 3 , 10 4 , and 10 5 ). In the view of grid independence, convergence and computational accuracy, a very popular Richardson extrapolation technique has been adopted [18,[21][22][23]. The relation is given by:…”

The present work aims at studying natural convection of nanofluids in a square enclosure embedded with a discrete heater at the bottom. The numerical simulations are performed using commercial software STAR CMM+ based on finite volume technique. Firstly, the results from the simulations are validated against the published results. Subsequently, numerical simulations have been carried out for predicting the flow and heat transfer characteristics of different water based nanofluids (Al 2 O 3 , Cu, TiO 2) at wide range of Rayleigh numbers, volume fractions, position of the heater and heater length. Results are presented in the form of streamline plots, isotherm contours and plots of average Nusselt numbers. It has been found that the average Nusselt number increases with increasing Rayleigh number, volume fraction, and heater length. Further, the effect of heater position on the flow and temperature fields for different nanofluids are discussed. However, Nusselt number was observed to be sensitive to the position of the heater.

“…The particle size effect is observed for different particle sizes of 50 nm and 150 nm. In addition to the Nanofluid, non-Newtonian fluid [12] to [18] is an alternative for working fluid. Compared with Nanofluids, non-Newtonian fluids widely exist and can easily be prepared.…”

In this research, an experimental study was performed regarding the heat transfer performance and pressure drop specifications of a Newtonian fluid and a non-Newtonian fluid. To this end, laminar flow of the deionized (DI) water and the aqueous solution containing 0.2 wt.% carboxyl methyl cellulose (CMC) were used as the Newtonian fluid and the non-Newtonian fluid, respectively, in wavy and straight mini-channel cross-flow heat exchangers (CFHE). Each mini-channel cross-flow plate heat exchanger (MCFPHE) was made of three copper plates for the hot and cold sides, which contain 27 mini-channels in parallel. The mini-channel CFHE was examined for Reynolds numbers (Re) in the range of 200 to 1800 and the hot-side inlet temperature was between 40 °C and 50 °C while the cold-side temperature varied in the range of 10 °C to 20 °C. The thermal and rheological properties of the non-Newtonian fluid were investigated. The results showed that for both fluids, the thermal performance of the wavy mini-channel is more than that of the straight mini-channel and, although the pressure drop was intensified, its effect is low at high Re values
