Investigation on Fluid Flow Heat Transfer and Frictional Properties of Al2O3 Nanofluids Used in Shell and Tube Heat Exchanger

Nanofluids are generally utilized in providing cooling, lubrication phenomenon, and controlling the thermophysical properties of working fluid. In this paper, nanoparticles Al2O3 added to base fluid, which flows through counterflow arrangement a turbulent flow condition. The fluids employed ethylbenzene water, have differing velocities on both tube shell side cylinders. A tube-type heat exchanger is used examine characteristics, friction loss, energy transfer as they pertain transmission thermal energy. findings proposed method showed that efficiency could be significantly improved by number, direction, spacing baffles. With inclusion 1% volume, property, rate can considerably improved. As result, Nusselt number Peclet numbers been increased 261 9.14 E +5. For mass 0.5 kg/sec, overall coefficient has also maximum value 13464. present investigation with nanoparticle addition 4.63% higher than Dittus–Boelter correlation. factor decreased about 17.5% 11.9% compared Gnielinski Blasius for was found 0.0376. It hence revealed suitable proportion along make remarkable changes behavior entire system.
