Heat transfer enhancement in a thermosyphon using TiO₂ nanofluid through natural convection

Performance of thermosyphon can be improved by using nanofluid where the colloidal suspension of nanosized TiO2 (1-100 nm) particle in the basefluid enhances the heat transfer characteristics of the base fluid. Therefore, a systematic study is made to characterise thermal conductivity of water based TiO2 nanofluid and then use in a circular finned thermosyphon to measure its thermal performance. The main novelty of the experimental investigation...
