...Se Young Yoon; Zongli Lin; Christopher Goyne; Paul E. Allaire The modeling of a centrifugal compressor system with exhaust and plenum piping acoustics is presented in this paper. For an experimental centrifugal compressor test rig with modular inlet and exhaust piping, a mathematical model...

... bearings (AMBs) of a compressor built for the experimental study of surge, the axial clearance between the impeller and the static shroud is servo controlled, and the measured variations in the compressor output flow are compared with the mathematical model. The steady state and the dynamic responses...

...Piotr Cyklis Pressure pulsations in volumetric compressor manifolds are one of the most important problems occurring in the compressor installations. They cause noise and vibrations, which may result in installation failures. In 2005 DOE USA ( Advanced Reciprocating Compression Technology (ARCT...

...Bin Xu; Quanke Feng; Xiaoling Yu Pressure pulsations in the piping system of the reciprocating compressor produce excessive noise and even lead to damage in piping and machinery. Therefore, it is very important to predict precisely the pressure pulsation with large amplitude in the piping system...

... accurate and reliable. The amplitude and frequency shown in Fig. 3 were obtained by the frequency analysis of the experimental and computed vertical displacements of the compressor end of the shaft. Trajectories of self-sustained rotor modes are also schematically shown in Fig. 3 . Graphs a and b...

...Jeong-Il Park; Nasir Bilal; Douglas E. Adams; Yoshinobu Ichikawa; Jacob Bayyouk This study predicts gas pulsations in the suction manifold of a multicylinder automotive air-conditioning compressor using a comprehensive simulation model of a reciprocating compressor. On the basis of the first law...

...Jeong-Il Park; Nasir Bilal; Douglas E. Adams This paper investigates the pressure pulsations caused by each mass flow rate through the suction valves and ports of a multicylinder compressor in order to attribute high-pressure pulsation responses to certain valves. By staggering the valve...

... converted form. For experimental demonstration, a test rig diverted from a high-speed compressor was used. The transfer functions were measured by exciting the control circuits with swept signals at rotor standstill and at its 30,000 revolutions/min rotational speed. For stability limit evaluation...

...Edmund A. Memmott, Mem. ASME This paper is intended to be a history of the usage of the Jørgen Lund rotordynamic programs in the analysis of centrifugal compressors from the perspective of the author’s experience in that industry. Application of the Lund tilt pad bearing, rotor response...

...Gyu-Sang Choe, Graduate Student; Kwang-Joon Kim, Professor Steady-state nonlinear response characteristics of a linear compressor are investigated theoretically and experimentally. In the theoretical approach, motions of not only piston but also cylinder are considered and dynamic models for steady...
