Review on Suitability of Ionic Liquids for Heat Transfer Applications

Divya P. Soman, P. Kalaichelvi, T. K. Radhakrishnan


The thermophysical properties of thermal fluids play a key role in the design of heat transfer equipment. Better their properties, greater is the efficiency of the heat transfer equipment. The field of ionic liquids (ILs) is growing, at a very fast pace, as many beneficial properties of these are identified and utilized. The suitability of the ionic liquids as thermal fluid can be assured by examining their thermophysical properties. In this paper, a review of the studies of thermophysical properties of ILs such as thermal conductivity, heat capacity, density and viscosity and their applications in heat transfer are highlighted. Basically, ILs are used as solvents and due to their favorable properties, they can be efficiently used in heat transfer applications also. Since there are more reviews on benefits of ILs available, in this review, applications of them in heat transfer are focused
