Abstract
The dual function of a surge tank is to reduce water-hammer waves in power station piping systems and to act as a rate-of-flow equalizer, from which immediate water or storage requirements following turbine load changes can be met. Design requirements are based on predictions of surging in the tank. Experimental performance figures from model and full-scale tanks are compared with various theoretical methods. Experimental investigations include comparison between the simple, widened, conical, throttled, differential and twin-type tanks, showing their uses and respective advantages. The effects of modifications of design are also examined. Finally, experimental results are presented which show the variation of water-hammer pressures with the different types of tank and system arrangement.
