HEAT TRANSFER IMPROVEMENT OF CROSS FLOW HEAT EXCHANGER USING HYBRID NANO FLUIDS EXPERIMENTALY

Abstract

The Requirement and need for a lot of powerful engines in smaller hood areas has created a lower rates heat
removation in cross flow heat exchanger (automotive radiators). Upwards of 34% of the energy generated by the
engine through combustion is lost in heat. To decrease the stress on the engine as results of heat generation,
automotive radiators should be redesigned to be a lot of compact whereas still maintaining high levels of
heat transfer performance. Base fluids (water and glycerol) are used as standard coolants in cross flow exchanger
device (automobile radiator) for several years; but, these offered low thermal conductivity phenomenon, that has
prompted researchers to search out fluids that supply and provide higher thermal conductivity
phenomenon compared to it of standard coolants. Nano fluids are thought-about as a new-type heat transfer
fluid due to their substantial increase in its heat removal rate, fluids viscosity, and heat
transfer coefficient. Planned work concentrates on developing experimental system to analyze the heat transfer rate
of cross flow device with hybrid nano fluids as a natural coolant and its CFD Analysis.
