    Abstract: The rotatable machine includes a compressor and an inner annular casing circumscribing at least a portion of the compressor. The inner annular casing includes a radially outer surface. The inner annular casing includes a radially outer surface, a vertically upper portion, and a vertically lower portion. The clearance control system includes a manifold system including a manifold system includes at least one conduit extending circumferentially around the vertically lower portion of the inner annular casing. The clearance control system includes a header system including at least one header extending circumferentially around only the vertically lower portion of the inner annular casing. The at least one header configured to receive a flow of cooling fluid from the at least one conduit. The at least one header configured to channel the flow of cooling fluid to the vertically lower portion of the radially outer surface of the inner annular casing.

    Abstract: A method of mitigating soak-back in a gas turbine engine including an engine core compartment and an active engine core compartment cooling system are provided. The active engine core compartment cooling system includes an aperture extending through a core engine cowl forming a radially outer wall of the engine core compartment. The active engine core compartment cooling system also includes a cooling fan mounted within the engine core compartment and including a cooling fan inlet and a cooling fan outlet. The cooling fan inlet is coupled in flow communication with the aperture. The cooling fan outlet is coupled in flow communication with the engine core compartment. The active engine core compartment cooling system further includes a cooling fan controller configured to at least one of control a rotational speed of the cooling fan and control a position of at least one flow control valve coupled in series flow communication with the cooling fan.

    Abstract: The rotatable machine includes a compressor and an inner annular casing circumscribing at least a portion of the compressor. The inner annular casing includes an outer surface in a radial direction, an upper portion in a vertical direction, and a lower portion in a vertical direction. The clearance control system includes a manifold system including at least one conduit extending circumferentially around the lower portion of the inner annular casing. The clearance control system includes a header system including at least one header extending circumferentially around only the lower portion of the inner annular casing. The at least one header configured to receive a flow of cooling fluid from the at least one conduit. The at least one header configured to channel the flow of cooling fluid to the lower portion of the outer surface of the inner annular casing.
