EXPERIMENTAL STUDY OF HEAT TRANSFER ENHANCEMENT OF CU-WATER NANOFLUID IN A HELE-SHAW CELL

The aim of study was to evaluate the effect of Cu-water nanofluids with different volume fraction of heat transfer in a Hele-Shaw cell. For this purpose a Hele-Shaw cell made of plexiglass screen (transparent) and withinthe chamber by the base fluid (water) and nanofluids (Cu-water) is filled. Hele -Shaw cell study heat transfer in many industrial applications including electronics and industrial cooling can be named. Increasing the volumefraction of nanoparticles increase the thermal conductivity of nanofluids increasing the amount of heat transfer. It is worth noting that the dramatic rise in energy costs is very useful in various industries. With increasingconcentrations of nanoparticles, nanoparticle interactions and collisions between more and the difference in temperature between the wall and the fluid will fall further and further improvement in heat transfer coefficient isobserved. The largest increases were nanofluids heat transfer coefficient for Cu-water nanofluids 0.04 per cent by volume showed that more than 32%.
