Abstract:

The hydraulic transient analysis HYTRAN computer program has been developed to simulate the response of a hydraulic system to sudden changes in flow demand by the system loads. For selected component temperatures, pump RPM, and initial steady state conditions, the program will calculate the pressures and flow amplitudes resulting from changes in flow demand or some other controller input. It will predict transient pressures due to waterhammer and the onset of cavitation due to the opening and closing of valves. The engineering input data to the program is normally available to a design engineer. When specialized components are required that are not covered by existing subroutines, these may be simulated by adding to the program.
