Preliminary Design and Optimization of Axial Turbines Accounting for Diffuser Performance
International Journal of Turbomachinery, Propulsion and Power, 2019 Axial turbines are the most common turbine configuration for electric power generation and propulsion systems due to their versatility in terms of power capacity and range of operating conditions. Mean-line models are essential for the preliminary design

Desensitization of Tip Clearance Effects in Axial Flow Turbines
Journal of Fluid Science and Technology, 2010 The present study aims to control the leakage flow and total pressure loss in high pressure turbines. A new tip shape is proposed. It is based on the triple squealer shape by adopting a new middle squealer, along the camber line, whose first and last ...
