Thermohydrodynamic Instability in Fluid-Film Bearings

Thermohydrodynamic Instability in Fluid-Film Bearings aims to establish instability criteria for a rotor-bearing system associated with fluid-film journal bearings.

• It focuses on how the influencing factors such as rotor flexibility, manufacturing imperfections such as residual shaft unbalance, and service-related imperfections such as uneven wear affect the stability of a rotor-bearing system
• It shows how the specific operating conditions such as oil inlet temperature, inlet pressure, and inlet position of a rotor-bearing system directly influence the system stability
• General design guidelines have been summarized to guide the engineering system design and the correction of failure and/or malfunction

J. K. Wang, PhD, PE has over 20 years’ academic and industrial experience in the design and vibration analysis of high-speed rotating machinery associated with fluid film bearings. Dr. Wang currently works as the Director of Engineering and Product Development of reciprocating and centrifugal pumps business units for TSC Group. He received his bachelor and master degrees from Xi’an Jiaotong University, and his doctoral degree from Louisiana State University. He is a professional engineer registered in the state of Texas, a certified Category IV Vibration Analyst, and Category IV Vibration Consultant listed by Vibration Institute. He holds the membership of ASME, ASM, SPE, and AISC.
