• The numerical modeling of rotor–stator rubbing in rotating

     · The rotor–stator rubbing is first observed in steam turbines around the 1920s since then, it became a challenging topic for many researchers. Newkirk and Taylor noticed that when a rotor rubs the stator below its first critical speed, the rub-induced lateral vibrations are amplified with the time. The phenomenon is named as “Newkirk effect.”
