N2 - In this paper, we present the visualization results obtained on the liquid flow in a pulsating heat pipe. Relative to their position in the condenser section, we measured the volume variations of bubbles as they moved through capillary tubes. For small heat fluxes, the bubble volume weakly depended on the distance. However, with an increase in the supplied power, the bubble volume changed significantly as the bubbles moved through the evaporator part due to evaporation of the liquid inside these bubbles. In addition, we employed an infrared scanner to perform a temperature distribution analysis and demonstrate the heat transfer processes.
