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.
