Study on Pulsations of Reciprocating Compressor Piping Systems : 1st Report, Calculation of Natural Frequency of Complicated Piping Systems

Pressure pulsations in reciprocating pump piping systems Part 1: modelling

A distributed parameter model of pipeline transmission line behaviour is presented, based on a Galerkin method incorporating frequency-dependent friction. This is readily interfaced to an existing model of the pumping dynamics of a plunger pump to allow time-domain simulations of pipeline pressure pulsations in both suction and delivery lines. A new model for the pump inlet manifold is also pro...

Coupling the Effects of Reciprocating Compressor Valve Dynamics with Piping Acoustic Response

Fluid Flow in Piping Systems

© 1989 Johnson Controls, Inc. 1 Code No. LIT-351H110 The relationship between the many factors which influence the pressure and flow rate within a hydronic system can sometimes seem very confusing. This report provides a simple systematic approach for analyzing basic hydronic systems. These concepts can later be applied to more complicated systems like those discussed in Engineering Reports H11...

Seismic Behavior of Welded Hospital Piping Systems

This paper presents findings from shake table experiments on cable-braced and unbraced welded hospital piping systems. The research identifies the capacity characteristics of a hospital piping system with and without bracings as well as the system’s weak points. The system was tested to the ICBO AC156 acceptance criteria for nonstructural components. The input motion of 1g was amplified to almo...
