... = latent heat of ammonia (kJ/kg) k = conductivity of absorbent (W/m °C) k l = instantaneous mass transfer coefficient (m/s) m = mean absorption rate (kg/s) m A = mean absorption rate in pure ammonia solution (kg/s) m N = mean absorption rate in binary nanofluid...

...Gui Lu; Yuan-Yuan Duan; Xiao-Dong Wang The nanoparticles used in present work were Al 2 O 3 , Cu, and CuO 2 , various particle volume fractions and diameters added into pure water to form the nanofluids. The thermophysical properties for the base fluid and nanoparticles are given in Table 1...

... transfer performance of two different nanofluids, namely, Al 2 O 3 -water and CNT-water has been studied experimentally in an automobile radiator. Four different concentrations of nanofluid in the range of 0.15–1 vol. % were prepared by the additions nanoparticles into the water as base fluid. The coolant...

... of harvesting solar radiant energy through usage of nanofluid-based concentrating parabolic solar collectors (NCPSC). In order to theoretically analyze the NCPSC, it has been mathematically modeled, and the governing equations have been numerically solved using finite difference technique. The results...
