CHAPTER SIX - Numeric and experimental investigations of performance improvement using nanofluids in car radiators

Abstract

This chapter discusses the recent advances of nanofluids application in car radiators. To minimize vehicle weight and improve overall performance, heat removal from the radiator must be improved. Radiators’ surface area and thermal conductivity must be enhanced to improve heat transfer. Thermal conductivity can be improved by improving the thermo-physical properties of heat transfer fluids, such as coolant. In recent years, the usage of nanofluids to improve heat transfer performance has grown. The fluids utilized nowadays are a mix of water and ethylene glycol. A hybrid nanofluid is a new type of nanofluid that combines two types of nanoparticles with a base fluid. This chapter’s focus is on hybrid nanofluids in car cooling systems. Nanofluids, which have exceptional thermal properties, are used in automotive engines, such as radiators, to aid in heat transmission. An experimental and numerical study comparing the performance of car radiators was recently published. Nanofluids as a cooling fluid: a thorough review of the relevance of cooling systems, coolants used in automobiles, applications, and limits.
