Parametric Investigation of Closed Loop Pulsating Heat Pipe with Cerium Oxide Nanofluid

In this study, a closed-loop pulsating heat pipe experimental investigation was done with 1% wt concentration of cerium oxide/EG-water (60-40) nanofluid. The unsteady state measurement to determine the effect input, filling ratio and evacuation pressure on thermal performance pipe. is assessed in terms temperature variation, resistance effective conductivity most appropriate behaviour observed at 0.0799 bar 50% FR. lowermost 0.116598K/W value as 5078.34 W/mK FR, for 80W input which 12 13 times better than pure copper. pulsation action inside verified power spectral density analysis. This study supports FR lower bar.
