Zusammenfassung:PROBLEM TO BE SOLVED: To provide a steam path design system and a computer program product.SOLUTION: Various embodiments include a system having at least one computing device (312) configured to design a flow path in a steam turbine (100) by performing actions including, for each component (107) in a set (307) of steam path components in the steam turbine (100): calculating an aspect ratio or radius ratio for the component (107); designing a shape of the component (107) on the basis of the calculated aspect ratio or radius ratio; determining a seal type for the component (107) on the basis of the calculated aspect ratio or radius ratio; and determining a size of a cavity (90) adjacent to the component (107) on the basis of the calculated aspect ratio or radius ratio, the shape of the component (107) and the seal type.SELECTED DRAWING: Figure 5 【課題】蒸気経路設計システム、コンピュータプログラム製品を提供する。【解決手段】様々な実施形態は、蒸気タービン（１００）の蒸気経路構成要素のセット（３０７）の各構成要素（１０７）に対して、構成要素（１０７）のアスペクト比または半径比を計算することと、計算されたアスペクト比または半径比に基づいて構成要素（１０７）の形状を設計することと、計算されたアスペクト比または半径比に基づいて構成要素（１０７）のシールタイプを決定することと、計算されたアスペクト比または半径比、構成要素（１０７）の形状およびシールタイプに基づいて構成要素（１０７）に隣接するキャビティ（９０）のサイズを決定することと、を含むアクションを実行することによって蒸気タービン（１００）の流路を設計するように構成された少なくとも１つのコンピューティングデバイス（３１２）を有するシステムを含む。【選択図】図５
