Mineral oils and other conventional fluids are excellent lubricants, but their weak thermal chattels limit their usage as industrial coolants. Various methods exist today for increasing the transfer heat rate for conventional fluids, including adding small solid particles (millimeters and micrometers) to conventional fluids to enhance their thermal properties. Despite this, these fluids have been associated with severe problems such as clogging, excessive erosion, pipeline pressure drops, and weak suspension stability. In the past decade, nanosized particles have replaced larger size particles in suspension, resulting in a novel class named nanofluids. Comparing these base- and nanofluids, nanofluids indicated well stability, more thermal conductivity, and minor pressure drop.
