Advanced Fluid System Simulation

Abstract

The report describes the continued development and test verification of digital computer models used to simulate hydraulic systems under dynamic conditions. A hydraulic acoustic generator was built and tested for frequency response work. Pulsation attenuation techniques are presented and several modifications were made to the Hydraulic Frequency Response Computer Program (HSFR) including a standing wave plot option. An empirical time domain pump model was developed and additional verification and development of the piston pump transient model was accomplished. Several enhancements were made to the Hydraulic Transient Analysis Computer Program (HYTRAN). A quasi-transient capability was added to the Steady State Flow Analysis Computer Program (SSFAN). The SSFAN Program was updated to extend the calculation capability, add new component models, program features, and reduce the program size. Several programming features were added to the Hydraulic Transient Thermal Analysis Computer Program (HYTTHA) including a temperature default section and environment section. Further verification work was accomplished on the HYTTHA program.
