Properties of silica nanofluid in glycerol-ethylene glycol mixture as base liquid

Base liquid properties are critical in heat transfer due to their flexible capabilities to suit a wide range of applications. The addition of two pure miscible liquids alters thermo-physical properties, which could in turn influence the desired heating or cooling performance. A binary mixture of eng...
