Abstract

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.
