1. A turbomachine, comprising:
a shaft rotatable about an axis of rotation; and
a damping device positioned annularly about the shaft, the damping device defining a radial direction and an axial direction, the axial direction parallel to the axis of rotation, the damping device comprising:
a bearing operatively coupled with the shaft;
a housing;
a damper element, the housing and the damper element defining a cavity therebetween for receipt of a damping fluid, the cavity having a curved shape; and
a support arm comprising a horizontal component between the damper element and a portion of the bearing, and a vertical component that extends in the radial direction towards the housing, wherein the support arm is configured to provide uniform distribution of the damping fluid within the cavity,
wherein the shaft extends longitudinally along the axial direction, and
wherein the cavity is curved in a plane extending along the radial direction and the axial direction and including the axis of rotation.
