NVESTIGATION ON THERMAL PERFORMANCE OF HEAT PIPE USING NANOFLUID: A REVIEW
Keywords:
Heat pipe, nanofluid, heat transfer enhancement, thermal performance, thermal resistanceAbstract
Nanofluids have been the subject of intensive study worldwide since pioneering researchers recently
discovered the anomalous thermal behaviour of these fluids. Comprehensive research work on heat transfer in
heat pipe using nanofluids have been experimentally and theoretically investigated in recent years by various
researchers. The suspended nanoparticles effectively enhance the heat transfer characteristics and the transport
properties of base fluids in heat pipes. The objective of this paper is to present an overview of literature dealing
with influence of various factors such as heat pipe tilt angle, charged amount of working fluid, nanoparticle type,
size and concentration, mass/ volume fraction & its effect on the thermal efficiency, heat transfer capacity &
reduction in thermal resistance.
