Nanofluid based Heat Exchanger

Nanofluids are the suspension of nanoparticles in the base fluid (water) that show significant enhancement of their properties. An investigation was carried out to study the performance analysis of shell and tube heat exchanger using two types of nanofluids namely CeO2/water and CeO2 + MWCNT/water. The cold water based nanofluids flow in tube side and water as hot fluid flows on shell side. Results indicate that hybrid nanofluid (90% ceria+10% MWCNT) has better heat transfer performance (incorporate the heat transfer rate, convective heat transfer coefficient, overall convective heat transfer coefficient, NTU and efficiency) compared to CeO2/water nanofluid (0.75% volume concentration).
