Turbomachine including clearance control system

A gas turbomachine comprising:

• a compressor portion;
• a turbine portion operatively connected to the compressor portion;
• a combustor assembly fluidically connected to each of the compressor portion and the turbine portion;
• a turbine casing extending about, at least in part, the turbine portion, the turbine casing including a body having an outer surface and an inner surface;
• and
• a clearance control system including a plurality of fluidically connected fluid channels extending between the outer and inner surfaces of the turbine casing, the plurality of fluidically connected fluid channels include a first fluid channel configured to direct a fluid flow in a first axial direction, a circumferential fluid channel configured to direct the fluid flow in a circumferential direction about the turbine casing, and a second fluid channel configured to direct the fluid flow in a second axial direction substantially opposite the first axial direction, the first fluid channel including a first outlet passing through the inner surface, and the second fluid channel including a second outlet passing through the inner surface.
