Non-Isothermal Hydrodynamic Characteristics of a Nanofluid in a Fin-Attached Rotating Tube Bundle

In the present study, a novel configuration of rotating tube bundle was simulated under non-isothermal hydrodynamic conditions using mixture model. Eight fins were considered in this which targeted hydrodynamics system. An aqueous copper nanofluid used as heat transfer fluid. Various operating factors, such rotation speed (up to 500 rad/s), Reynolds number (10–80), and concentration (0.0–4.0%) applied, performance microchannel exchanger assessed. It found that coefficient system could be enhanced by increasing number, nanofluid, speed. The maximum enhancement (HTC) 258% after adding 4% volumetric nanoparticle base fluid Re from 10 80 ω 0 rad/s. Furthermore, at = rad/s, HTC values measured for 42.3% higher than those calculated water, showing nanoparticles’ positive impact on paradigm. Moreover, it identified presence had no significant effect system’s pressure drop. This attributed interaction flow circulated around tubes. Finally, drop considerable changes when augmenting high numbers.
