AN EXPERIMENTAL INVESTIGATION OF THE THERMAL PERFORMANCE OF TWO-PHASE CLOSED THERMOSYPHON (TPCT) USING ZIRCONIA (ZrO2/H2O) NANOFLUID

Abstract

In this work an avant-garde study is made to find out the thermal performance of two-phase closed thermosyphon (TPCT) using ZrO2 (5 - 25 nm) nanoparticle with base fluid water. The TPCT is fabricated from the copper tube with the outer diameters of 6mm, 8mm and length of 800mm. The concentration of nanofluid is varied from 3% and 4% by weight. The experimental work is carried out under different operating conditions. The input parameters such as effects of input power, fill ratio and nanoparticle concentration on the thermal efficiency and thermal resistance of the TPCT were investigated, compared and discussed. From the results, it is observed that the efficiency of the TPCT increases when ZrO2/water nanofluid was used instead of water.
