The chronological study on parametric evolution of pool boiling with nanofluids: An experimental review

Abstract

• Summary of chronological survey for research articles and review articles. • Identification and evolution study of parameters affecting nanofluid pool boiling. • Summary of experimental procedures and novel schematics. • Statistical comparison for evolution of research methods over decades. • Proposal for future scope of research with interdisciplinary technologies. The present review work focusses on parametric evolution in pool boiling heat transfer with nanofluids. The design philosophy for new setup schematics are presented along with various uncertainty analyses procedures. The effect of new parameters viz. ambient pressure, boiling time, electric and magnetic fields, repetitive quenching and novel surfaces is discussed. The compilation of effects of basic parameters viz. nanoparticle concentration, nanoparticle size and base fluids is also presented. The timeline comparison revealed the exploration of multiple nanoparticles and base fluids combinations for enhanced performance in pool boiling parameters. The development of object oriented setups and uncertainty techniques provided better benchmark for future studies. It was evaluated that the studies focussed with nanoparticle concentration and size as variable parameters, revealed heat transfer coefficient (HTC) variations ranging from ∼ -50 % to ∼ 200 %. Similarly, critical heat flux (CHF) variations were noted to vary from ∼ 20 % to ∼ 300 %. The empirical nature of the studies attributed the high range of variations to physical effects of surface-fluid-nanoparticle interactions. The studies with evolution parameters presented clearer insights for HTC and CHF enhancements. The pressure variation affects revealed ∼ 300 % CHF and ∼ 130 % HTC enhancements. Similarly, boiling time assessment showed access of ∼ 250 % CHF enhancements with increasing boiling durations. The repetitive quenching analysis discussed accelerated quenching velocity fronts, indicating rapid cooling with nanofluids. The presence of electric and magnetic field resulted controlled pool boiling behaviours with ferromagnetic nanofluids. Similarly novels heater surface designs and sonication methods indicated HTC and CHF enhancements of ∼ 100 % and ∼ 200 %, respectively, with minimal nanoparticle depositions.
