“…The nanofluid in these studies consists mainly of CuO/water [1,2], CuO/ethylene glycol [3], Al 2 O 3 /ethylene glycol [3,4], Al 2 O 3 /water [4][5][6][7][8][9], Al 2 O 3 /ethylene glycol/water [10], TiO 2 /water [8,11], and Ag/methanol nanofluid [12]. Moreover, heat exchangers used in these studies include the microchannel heat sink (MCHS) [1,7,10], miniature-plate heat exchanger [2], plate heat exchangers [3], double-tube flow heat exchanger [3,11], multichannel heat exchanger [5], shell and tube heat exchanger [8], finned tube heat exchanger [9,13], and the thermosyphon heat exchanger [12]. Results of these studies demonstrate that nanofluid could improve the performance of heat exchangers.…”

This study analyses the density and specific heat of alumina (Al 2 O 3 )/water nanofluid to determine the feasibility of relative calculations. The Al 2 O 3 /water nanofluid was produced by the directsynthesis method with cationic chitosan dispersant served as the experimental sample, and was dispersed into three concentrations of 0.5, 1.0 and 1.5 wt.%. This experiment measures the density and specific heat of nanofluid with weight fractions and sample temperatures with a liquid density meter and a differential scanning calorimeter (DSC). To assess the availability of these equations, it then compares the experimental data with the calculated results according to the concepts of mixing theory and statistical mechanism. Comparing the calculated results of density and specific heat with the experimental data, the deviation of density fell within the range of À1.50% to 0.06% and 0.25% to 2.53%, whereas the deviation of specific heat fell within the range of À0.07% to 5.88% and À0.35% to 4.94%, respectively. Calculated results of density and specific heat show a trend of greater deviation with an increased concentration of nanofluid. However, two kinds of density and specific heat of the calculated results fall within an acceptable deviation range in this study.

“…They showed that the cooling performance of a MCHS with water-base nanofluids containing diamond (1%, 2 nm) at fixed pumping power of 2.25W was enhanced by about 10% compared with that of a MCHS with water. There have been relatively few recent studies on nanofluid flow and heat transfer characteristics as comparing with those of pure fluid [14][15][16]. These studies showed that the heat transfer coefficient was greatly enhanced using nanofluid compared with pure fluid although there is a slight increase in pressure drop due to the presence of nanoparticles in MCHS operation.…”

“…For instance, in the laminar and turbulent flow of heat exchangers [1][2][3][4][5] , horizontal and vertical tubes [6][7][8][9][10][11][12][13][14] , microchannel [15][16][17] , etc. Bajestan et al 1 considered the Brownian motion as the dominant mechanism of heat transfer in laminar flow.…”
