Study on Effect of Surfactants on Dispersion Characteristics of Nanofluids

Nanofluids are the new engineering materials which comprise of nanometre size particles as an improver to modify the properties of common fluids to be suitable in various applications. The biggest issue in nanofluids is the settling of nanoparticles due to agglomeration among particles in the liquid...
