PROBLEM TO BE SOLVED: To provide a turbomachine or a turbine casing with a clearance control system.SOLUTION: A turbine casing 30 includes a body having an outer surface and an inner surface, and a clearance control system 51 includes a plurality of fluidically connected fluid channels 54 extending through the turbine casing. The plurality of fluidically connected fluid channels 54 include a first fluid channel 56 configured to direct a fluid flow in a first axial direction, a circumferential fluid channel 67 configured to direct the fluid flow in a circumferential direction, and a second fluid channel 58, 60 configured to direct the fluid flow in a second axial direction substantially opposite the first axial direction. The first fluid channel 56 includes a first outlet passing through the inner surface, and the second fluid channel includes a second outlet passing through the inner surface.SELECTED DRAWING: Figure 4 【課題】クリアランス制御システムを備えたターボ機械又はタービンケーシングを提供する。【解決手段】タービンケーシング３０が外表面及び内表面を有する本体を含み、クリアランス制御システム５１は、タービンケーシングを通って延びる複数の流体接続された流体チャンネル５４を含む。複数の流体接続された流体チャンネル５４は、流体流れを第１の軸方向に配向するよう構成された第１の流体チャンネル５６と、流体流れを円周方向に配向するよう構成された円周方向流体チャンネル６７と、流体流れを第１の軸方向と実質的に反対の第２の軸方向に配向するよう構成された第２の流体チャンネル５８、６０と、を含む。第１の流体チャンネル５６は、内表面を通過する第１の出口を含み、第２の流体チャンネルは、内表面を通過する第２の出口を含む。【選択図】図４
