Modified self-consisted scheme to predict the thermal conductivity of nanofluids

A review of nanofluid stability properties and characterization in stationary conditions

“…The surface charge state is a basic feature which is mainly responsible for increasing thermal conductivity of the nanofluids [52,53]. Also in some experiments particles' shape conversion was related to the pH variation [49,55].…”

“…13. Likewise, Hadjov et al [55] assumed a flux jump and a discontinuity between the inclusion and the matrix as well which is called the thermal conductive interface. This assumption conflicts with the previous model.…”

Thermal conductivity, viscosity and heat transfer process in nanofluids: A critical review

“…By controlling the repulsive force between nanoparticles, the zeta potential is decreased to zero at a particular pH value at the isoelectric point and it is a negative problem for the stability of nanofluids [35]. The pH deviation of a prepared suspension from the isoelectric point increases the stability of colloidal particles and causes the changes in the thermal conductivity of the nanofluid [208]. Jorge et al [209] investigated the MWCNT/water nanofluid at pH values of 2 and 5.5 and reported that the mentioned nanofluids were stable because of the deposition of amines on the MWCNT surface.…”
