Assessment of Large-Eddy Simulations to Simulate a High-Speed Low-Pressure Turbine Cascade
International Journal of Turbomachinery, Propulsion and PowerThe development of compact high-speed low-pressure turbines with high efficiencies requires the characterization of the secondary flow structures and the interaction of cavity purge and leakage flows with the mainstream.

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 ...

TurboFlow: Meanline Modelling of Axial Turbines
Journal of Open Source SoftwareMeanline modeling is a fundamental approach used in the design and analysis of axial turbines (Dixon, 2014). The method simplifies the analysis by assuming a uniform flow and incorporates semi-empirical correlations to estimate performance. This approach allows for a reasonably accurate approximation at low computational cost.TurboFlow is a Python ...

Modeling of Turbine Engine Axial-Flow Compressor and Turbine Characteristics
Journal of Propulsion and Power, 2000 The paper describes the concept of modeling the turbine engine axial-flow compressor and turbine characteristics by using the function of two variables. Accuracy of the proposed concept has been verified on the example of the given compressor and turbine characteristics.
