Abstract: Methods, systems, and apparatus are disclosed to provide a pressurized fluid to components of a fluid pump. An example flow control system to provide a pressurized lubricant to a secondary flow network disposed within a fluid pump includes sensors to measure parameters of a fluid corresponding to fluid flow; a recirculation loop fluidly coupled to a secondary inlet of the pump, the recirculation loop to provide a first flowpath, wherein the secondary inlet is an inlet to the secondary flow network; a bypass circuit fluidly coupled to the secondary inlet to provide a second flowpath; and a controller to direct the fluid flow to the first flowpath or the second flowpath based on sensor data from the sensor, the sensor data indicative of a state of the fluid.

Abstract: A seal assembly for a gas turbine includes a seal case, and a seal shoe arranged within the seal case. The seal shoe includes a main seal portion that is configured to engage with a radial bearing engagement portion of a rotor shaft, a radial bearing surface that engages with the radial bearing engagement portion of the rotor shaft, at least one hydrodynamic lift cavity extending through the radial bearing surface, and at least one airflow passage extending from a first side of the seal shoe through the at least one hydrodynamic lift cavity and providing airflow communication between the first side of the seal shoe and the at least one hydrodynamic lift cavity.
