Abstract

Abstract

Two different types of pressure drop characteristics of flow damper were obtained through the test of pressure drop characteristics of flow damper in advanced accumulator. The influence law of different geometric parameters on the pressure drop coefficient is studied, and the relationship of pressure drop coefficient is fitted. The results show that in the range of experimental parameters, the vortex pressure drop coefficient increases gradually with the increase of Reynolds number, and the mixing pressure drop coefficient decreases rapidly and then increases slowly with the increase of the flow ratio of large tube to small tube. The small tube width and flow damper diameter have a certain influence on the vortex pressure drop coefficient. The inclination of large and small tubes, the flow damper diameter and the large tube width have an effect on the mixing pressure drop coefficient, while the small tube width has no obvious effect on the mixing pressure drop coefficient. The deviation between the predicted value of the vortex pressure drop coefficient relationship and the experimental value is within ±10%, and the deviation between the predicted value of the mixing pressure drop coefficient relationship and the experimental value is large.
