Computer-aided acoustic analysis of reciprocating compressor pipeline systems
Tóm tắt
This paper presents an analytical method for acoustic forced pulsations of reciprocating compressor pipeline systems have a treelike structure that consists of an arbitrary number of branchings with optional elements—pipes, volumes, orifices, and so on. The plane wave acoustic model is used to describe the method, and the solution works by using an extended Schmidt-Kuhlmann-type approach. On the basis of a graph and matrix interpretation of the structure, a generalized algorithm is developed for determining the actual terms that describe the transfer properties of the system and to help calculate the acoustic pressure and velocity pulsations. The algorithm makes it possible to mechanize programming in the case of both natural frequency and forced pulsation calculations. The program package developed here for the personal computer can be directly applied in the design practice with success. It is also applicable to other linear systems with treelike structures.
