On the Chief Dimensions of an Axial Flow Propeller Turbine

Transactions of the Society of Mechanical Engineers, 1935
軸流プロペラ水車に於て導き羽根入口から羽根車入口迄の損失、羽根車内の損失、羽根車出口から下水溝迄の損失の合計が最小になる様な條件から水車寸法を決定するに必要な諸係數を比較回轉度の函數として示したものである。

Numerical Study of Wake Characteristics in a Horizontal-Axis Hydrokinetic Turbine

Anais da Academia Brasileira de Ciências
Over the years most studies on wake characteristics have been devoted to wind turbines, while few works are related to hydrokinetic turbines. Among studies applied to rivers, depth and width are important parameters for a suitable design. In this work, a

Variable turbine geometry for an automotive turbocharger with a small axial turbine

Proceedings of Global Power & Propulsion Society
The paper examines the implementation of a variable turbine geometry (VTG) and the reduction of its tip leakage losses in a small axial turbine turbocharger for charging lean-burn internal combustion engines. Due to the small turbine size, a reduction in the number of vanes and a redesign was required to match the design point of the non-adjustable ...
