EFFECT OF SURFACTANT ADDITION ON THE NANOFLUIDS PROPERTIES: A REVIEW
The applications and usage of surfactants in the field of nanofluids heat transfer and its stability were performed the present literature review. The usage of surfactants has been employed for the following areas of nanofluids study: nanofluid heat transfer, nanofluid agglomeration and nanofluid enhancement stability. Generally, a few interesting has been achieved to study the effects of using the surfactants on the nanofluids properties such as pH, thermal conductivity, specific heat, electrical conductivity, viscosity and stability mechanism of nanofluid. The using nanofluid in real applications is taken into consideration by two key issues emerge: erosion and settlement but there aare possible difficulties related to these issues that need to be studied and solved prior to the using of nanofluid in commercial applications. In addition, this paper summarizes the theoretical and experimental studies on the effects of applied various types of surfactants in nanofluids. This work can serve as a ready reference for application of surfactants in nanofluids.
