Abstract

This paper reports on research aimed at developing and evaluating a theoretical method of analyzing the performance characteristics of the water-pumping hydraulic ram. Results indicate that analytical solutions of one-dimensional equations, which describe unsteady flow during the drive and pumping cycles, lead to relationships that can be conveniently used for an accurate prediction of hydram characteristics under low drive heads. These relationships, however, do not perform as well under higher drive heads, and the primary reason for which would appear to be the simplifying assumptions that have to be made so that an analytical solution can be found. In particular, the assumption of constant drive and delivery valve loss coefficients is thought to be the primary source of error. An alternative approach for overcoming this difficulty is discussed.
