Properties and Potential Applications of Carbon Nano Horns Over Carbon Nano Tubes as a Nano Fluid - A Review

Abstract

Abstract Nano fluids play a vital role in enhancing the performance of major thermal systems such as heat exchangers, Refrigeration & Air conditioning systems, Internal Combustion Engines. Among those carbon nano tubes is the most predominantly used nano particle. But the major problems associated with the carbon nano tubes are poor stability and lower dispersion in excess saline environment which leads to fouling in heat exchangers which in turn reduces the heat transfer rate when used as a nano fluid. Therefore in this review article properties such as thermal conductivity, thermal diffusivity, viscosity etc., potential applications and merits of carbon nano horns (which is synthesized by structural modifications of carbon nano tube) over carbon nano tubes when used as a nano fluid has been discussed.
