Part of: Hydraulics and Hydrology in the Small Computer Age


In this paper a digital simulation technique for the analysis of resonance is presented that is appropriate for microcomputer applications. The model utilizes the transfer matrix method to compute, in the frequency domain, the propagation of pressure waves through the system and the establishment of oscillatory flow. It produces results of equal validity to analog simulations at a fraction of the time and cost. The simulation technique has been applied to hydraulic systems as diverse as sludge piping in a wastewater treatment plant, a hydraulic muffler and the emergency cooling system of a nuclear power plant.
