Finger seals, that contain padded low pressure laminates, are compliant seal configurations that can be designed to function as non-contacting seals. Unlike brush seals, due to the padded elements, they exhibit hydrodynamic lifting capabilities which allow non-contact sealing between stationary and rotating members. Through elimination of rub between the seal and the rotor, this configuration presents the user with the advantage of a potentially unlimited lifespan and reduced maintenance. The model presented here uses a commercial package CFD-ACE+ for the fluid calculations and a stress module combined with a mesh deformation module for the compliant solid calculations, respectively.
