Investigation of pH and SDBS on enhancement of thermal conductivity in nanofluids

Effects of pH on the zeta potential and particle size of nanofluids with SDBS. Concentration of nanoparticles and SDBS are 0.05% weight fraction, respectively. The error bars which indicate standard deviation over 10 consequent measurements. The heat transfer enhancement of two water-based nanofluids was investigated under different pH values and different sodium dodecylbenzene sulfonate concentrations.
