Religion played a prominent role in the 2020 presidential campaign. Donald Trump overtly courted white evangelical Protestants and Catholics, while Joe Biden emphasized his Catholicism far more than any Catholic candidate in American history. Did rel

Atheoretical model has been developed for a synchronous thermal instability that is caused by differential viscous shearing in bearings of overhung rotors. This model employs an unbalance threshold criterion for instability instead of utilizing a tra

In Part I, a theoretical model was developed for a synchronous thermal instability that is caused by differential viscous shearing in bearings of overhung rotors. This second part used computer programs, which were based on the theoretical model, to

Labyrinth seals in various kinds of rotating machinery often generate driving force components that may increase the unstable vibration of the rotor. The evaluation of labyrinth seal forces has been documented by CFD analysis but the leak path geomet

Diesel engine turbochargers are known to have operation into the self-excited unstable region. The operation in the nonlinear limit cycle has been tolerated on most applications to date. The need for a quieter and a smoother operation and in addition

Automotive turbochargers are known to have operation into the linear unstable region. The operation in the nonlinear limit cycle has been tolerated on most applications to date. The need for a quieter, smoother operation and reduced emissions has pro

This paper will discuss the unexpected high vibration seen on both the drive end and the driven end of a high-speed disc pack design coupling, in addition to the documented vibration at the coupling spacer mid-span location. The coupling was being us

The use of active magnetic bearings (AMB) for turbomachinery has experienced substantial growth during the past two decades. The advantages for many applications make AMB’s a very attractive solution for potentially low loss and efficient support f

This paper presents a finite element solution of the nonlinear and coupled hydrodynamic and thermal equations for pressure and temperature distributions in two-lobe oil seals. The pressure distribution is integrated to obtain hydrodynamic forces. The
