Rotor Dynamic Analysis of Centrifugal Compressor due to Liquid Carry Over

This paper shows a study of rotor dynamic response of centrifugal compressor due to liquid carry over. The rotor system is supported by supporting structure bearings with different stiffness. This case study shows the rotor dynamic analysis of a Jeffcott rotor. From the study of rotor dynamic on Jeffcott rotor, the results are as follows; Campbell Diagram, critical speed, mode stability and whirl orbits. By using different value stiffness bearings, the results will be further discussing in results and discussion. The simulation of rotating rotor will be executed in ANSYS Mechanical APDL. With the simulation, the research can achieve the objectives.
