Influence of pH on the Stability Characteristics of Nanofluids for Heat Transfer Applications

Nanofluids have been in intense researches for the past few years with the great potential to improve the efficiency of heat transfer fluids. Knowledge of sediment behaviours of nanofluids give great significances towards the stability of nano-suspensions. This work focuses on the sedimentation beha...
