A Study of the Application of Newtonian Fluids in Heat Transfer

Abstract

This paper reviews the experimental and numerical findings on the impact of Newtonian fluids in heat transfer. Newtonian fluids are characterized by a constant viscosity that does not depend on the shear rate. They are commonly used in heat transfer applications because they exhibit predictable and stable flow behaviour, making them easier to model and analyze. A popular application of Newtonian fluids in heat transfer is electronic cooling. The heat generated by electronic components can be dissipated by circulating the Newtonian fluids, such as water or oil, through a cooling system. Newtonian fluids are also used as heat transfer fluid in heat exchangers, which use a series of tubes to transfer heat between two fluids separated by a conductive barrier. Newtonian fluids are also used for industrial processes like mixing and agitation in mixing tanks and reactors to transfer heat between different phases or to maintain a consistent temperature within the vessel. The predictable behaviour and low viscosity make Newtonian fluids efficient in heat transfer across the barrier. This study explores the use of Newtonian fluids in heat transfer applications in both industrial and consumer settings.
