Abstract

When nanofluid (NF) is used as the working fluid in a rectangular two-phase closed thermosyphon (RTPCT), the formations and heat performance of two-phase flow patterns are explored qualitatively. Silver nanoparticles were mixed with deionized water at a concentration of 0.5 wt% in the NF. Nanoparticles improved the thermal contact surface area within the base flow, allowing the base fluid to boil quickly and easily. When the working fluid was boiled, NF also demonstrated high thermal conductivity capabilities, which diffused and moved along with the dual flow patterns. As a result, these qualities improved the RTPCT's efficiency. Considering the findings of the RTPCT test at evaporation temperatures of 50, 70, and 90o C, three flow forms are observed: bubble flow (BF), slug flow (SF), and churn flow (CF), respectively. The slug flow (SF) and the churn flow (CF) are patterns that influence the heat flux. The greatest heat flow obtained from the test is 4.78 kW/m2 at 90°C evaporation temperatures, whereas the heat flux measured at 70°C and 50°C evaporation temperatures is 2.95 kW/m2 and 2.74 kW/m2 , respectively.
