Abstract: The fluctuant phenomenon of fluid circulation appears in the starting and working processes of two-phase capillary pumped loops(CPL).This problem was preliminarily studied by experiment.The origins of the fluctuant phenomenon were analyzed and the fluctuant situations of pressures and temperatures in the inverted type evaporator were investigated.The variation regularity of the output pressure in the evaporator in different conditions were obtained.
