Numerical investigation of the effects of design parameters on hydraulic turbine guide vane design

Öz:
Francis type hydraulic turbines that have a wide range of operatingrange for head and flow rates are commonly used in hydropowergeneration. Every power plant needs its custom designed turbinebecause the available head and flow rates, which are the mainparameters to start the design process, are different for each plant.Guide vanes are the only movable parts of Francis turbines. They controlthe flow rate through the turbine. In this study, a generalizedComputational Fluid Dynamics (CFD) aided design methodology isdeveloped and applied to the design of the turbines of two differentpower plants. The effects of several parameters, including the shape ofthe guide vane profile, eccentricity, blade angles, overlappingpercentage of the blades, number of guide vanes, and rotor-statordistance are examined. Results are investigated for each parameter interms of flow physics and important outcomes are determined forturbine designers.

Tasarım parametrelerinin hidrolik türbin ayar kanadı tasarımına etkilerinin sayısal olarak incelemesi

Öz:
Francis tipi su türbinlerinin çeşitli debi ve düşü değerlerini kapsayan geniş bir çalışma aralığı olduğu için güç üretiminde sık kullanılırlar. Her hidroelektrik santralin kendi özelliklerine uygun türbin tasarımına ihtiyacı vardır; çünkü türbin tasarım prosesinin en önemli iki parametresi olan düşü ve debi her santral için farklıdır. Ayar kanatları türbinin tek hareket ettirilebilen parçasıdır. Türbinden geçen debiyi düzenlemeye yararlar. Bu çalışmada, Hesaplamalı Akışkanlar Dinamiği (HAD) bazlı bir genelleştirilmiş tasarım yöntemi geliştirilerek iki ayrı hidroelektrik santralin türbin tasarımına uygulanmıştır. Ayar kanadı profili, merkezden kaçıklık, kanat açıları, kanatların örtüşme yüzdeleri, ayar kanat sayısı, rotor-stator mesafesi gibi tasarım parametrelerinin etkileri incelenmiştir. Sonuçlar her bir parametre için incelenmiş, akış fiziği ve türbin tasarımcıları açısından önemli bulgular belirlenmiştir.
