Dynamics of Propellant Feedline Systems

Abstract

In this investigation, a generalized computer code for the simulation of fluid transients was assembled, verified, and applied. The solution method developed for the program was based on a method of characteristics solution of the equations of motion for one-dimensional fluid flow in pipelines. The differential equations were solved using a first-order finite difference technique. Boundary conditions for the equations of motion were developed or directly included from available component models. The computer routines were verified from several sources. The agreement between the results of this study and the published data was quite good for a wide range of boundary conditions and pipe systems. Recommendations were made for improvement of some models and the replacement of others to further improve the accuracy of the results.
