    Theoretical modelling and experimental verification of the heat transfer behaviour of a water-charged closed-end loop pulsating heat pipe
    (2001) Swanepoel, G.; Dobson, R. T.; Taylor, A. B.
    ENGLISH ABSTRACT: In this paper the theoretical modelling of a Pulsating Heat Pipe (PHP) is presented. In this particular model the flow of the working fluid is modelled as discrete liquid plugs moving back and forth because of the evaporation and condensation processes taking place inside of the PHP. A PHP was manufactured to determine the heat transfer rate of the PHP experimentally and to compare the experimental results with the theoretical results. The average heat transfer rate predicted by the theoretical model in the top heat mode was 62 W compared to the experimental value of 60 W. In the bottom heat mode the average theoretical predicted heat transfer rate was 86 W compared to the experimental determined value of 65W.
