Thermal analysis of acetone and water in closed loop pulsating heat pipe

Thermal conductivity and transition are the two stages of a closed loop pulsating heat pipe's operation. A device called a closed loop pulsating heat pipe transfers heat at various heat inputs. The thermal performance of the closed loop pulsating heat pipe is impacted by various types of modifications. Heat transfer characteristics of the closed loop pulsating heat pipe are to be ob-served using computational fluid dynamics analysis. The aim of this study is to improve the heat conductivity of the closed loop pulsating heat pipe with the changing filling ratio. This study presents the closed loop pulsating heat pipe modeling by using ANSYS Workbench. ANSYS Fluent is considered to model the above stated phenomenon and computational fluid dy-namics simulations are performed for different variations of temperature and filling ratio. The model is analyzed at 200W300W heat flux for 100400 iterations and the vaporized form is obtained. The temperature and iterations variations are the key parameters of the study. It is concluded that the temperature of the evaporator increased more at different levels of time as compared to the temperature of the condenser. In this analysis, by giving different heat inputs and evaporator sections, the heat flux in the condenser section is observed. It is concluded that the time and heat flux are the most affecting parameters in this study.
