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
