Summary:PROBLEM TO BE SOLVED: To provide a turbomachine combustor that reduces turbulence in an airflow flowing to a head end to enhance combustor performance.SOLUTION: A turbomachine combustor includes a combustor body extending from a head end to a discharge end. The combustor body includes a combustor liner defining a combustion chamber. A combustor sleeve surrounds the combustor liner. The combustor sleeve is arranged at a distance from the combustor liner, forming a passage. The combustor sleeve includes at least one opening. A baffle is arranged in the passage. The baffle includes a curvilinear surface extending from the combustor sleeve across the at least one opening toward the head end of the combustor body. The baffle is configured and arranged to compress a fluid flow flowing through the passage toward the head end. 【課題】ヘッド側端部へ流れる空気流の乱れを減らして燃焼器性能を向上させるターボ機械の燃焼器を提供すること。【解決手段】ターボ機械の燃焼器は、ヘッド側端部から出口側端部まで延在する燃焼器本体を含む。燃焼器本体は、燃焼室を画定する燃焼器ライナを含む。燃焼器スリーブは燃焼器ライナを囲む。燃焼器スリーブは、燃焼器ライナから間隔を置いて配置されて通路を形成する。燃焼器スリーブは少なくとも1つの開口を含む。バッフルは通路内に配置される。バッフルは、燃焼器スリーブから、少なくとも1つの開口を横切って燃焼器本体のヘッド側端部へ向かって延在する曲線状の面を含む。バッフルは、通路を通ってヘッド側端部へ向かって流れる流体流を圧縮するように構成および配置される。【選択図】図1
