Abstract :
Cooling is one of the most important challenges in saving energy and increasing the productivity of many industries. The first serious obstacle in compressing and making heat transfer devices more efficient is the weak properties of heat transfer fluids. The energy efficiency of heat transfer equipment depends on the heat flux changes created in them. The use of common fluids such as water and ethylene glycol as cooling fluids in the cooling system of various heat transfer devices is not the answer to the removal of very high heat flux (tens of megawatts per square meter). Today, nanofluids are made as new heat transfer fluids by adding nanoparticles to fluids that have low heat transfer and by creating changes in the density, specific heat and viscosity of these fluids in order to increase thermal conductivity and improve heat transfer performance. In this research, the results of laboratory research on heat transfer in nanofluids under laminar, turbulent flows and pool boiling are discussed and investigated.
