Download attached document Overview: PULS (Pulsations Simulator), originally developed by NOVA-HUSKY Research Corporation, Calgary, is a generalized and comprehensive acoustic simulation program.  Its primary use is for the control of excessive steady pressure pulsation in natural gas pipeline systems. SSD Engineering consultants have added a few new capabilities to PULS, including liquid system handling.  PULS elements are based on extensive research and testing done at NOVA HUSKY Research Corporation test facilities. Acoustic analysis is performed in order to prevent pulsation problems after system startup. The program can also be used to determine modifications required to existing systems due to a pulsation problem. PULS is able to simulate the pulsation response to reciprocating compressors and pumps as well as flow-generated sources, such as control valves and vortex-generated pulsation at tee junctions. PULS is ideally suited for reciprocating compressor bottle sizing according to the American Petroleum Institute (API 618) guidelines and will evaluate the properties of natural gas mixtures using AGA-8 equation of state.  What does it do?  Performs Pulsation Studies for reciprocating compressors per API 618 design approaches II and III Sizes pulsation bottles or filters for reciprocating equipment Perform pulsation studies on reciprocating pumps Evaluates flow induced vibrations caused by flow past tees and valves Evaluate acoustic mode shapes and frequencies AutoPIPE-like CAD Graphical Interface GRIDS Color Plots Graphical Input & Result Data Unique Features Interactive Graphical Interface for input and output or import model from AutoPIPE Analyzes steady pulsations caused by reciprocating compressors/pumps or by flow induced vibration caused by tees and valves Uses Plane Wave Theory and Transfer Matrix Based on Multi-Million research program at NOVA corporation in Calgary, Canada.
