Experimental Studies on Helical Coiled Heat Exchanger with Al2O3/Water Nanofluid

Sandeep Parma and B.S.V.S.R. Krishna

Abstract

The nanomaterials dispersion in fluid is effective to improve the thermal/physical properties of fluids. Secondary flows created by helical coils may improve the mass and heat transfer. Usage of nanofluids in heat transfer may improve the heat transfer coefficient. Present study focused on the heat transfers of a shell and helical coil tube heat exchanger using water as base fluid with aluminum oxide (Al2O3) nanoparticles at 0.01, 0.02 and 0.05 volume % concentration and different flow rate were tested at constant wall temperature as boundary condition. Water as shell side fluid and Al2O3/water nanofluid as in coil side were studied with different dean number. Change in heat transfer due to use of Al2O3/water nanofluid has been observed in terms of heat transfer rate.
