A model of a liquid bridge, which is formed between adjacent turns of an axisymmetric tubular heat exchanger, has been developed. The shape of the free surface of the bridge cross-section is determined taking into account the forces of liquid ponderability, surface tension, and centrifugal forces. The equations for the coordinates of the points of bridge free surface are presented in an integral form based on the problem solution in the analytical form. The effect of centrifugal forces on the liquid bridge shape and its flow characteristics were analyzed for an axisymmetric heat exchanger, basing on calculations of the shape of the bridge and known data on the speed of the bridge.
