Abstract

Stability analysis in the framework of fluid dynamics is often expressed in terms of a complex eigenvalue problem (EVP). The solution of this EVP describes underlying flow features and their stability characteristics. The main shortcoming of this approach is the high computational cost necessary to solve the EVP, limiting the applicability of this analysis to simple two-dimensional configurations. Many efforts have been focused on overcoming this limitation. Reducing the computational domain to encompass only those regions of physical interest may help alleviate the computational cost. However, the accuracy of the eigenmodes recovered from a reduced region needs to be carefully assessed. In this work, an in-depth analysis of the domain reduction (DR) strategy is presented, and an error estimation tool is provided. The applicability and limitations of this methodology are studied on the open-cavity problem. Next, the error estimation tool is exploited in the transonic buffet phenomenon on a NACA 0012 profile, giving valuable recommendations for the best use of this methodology. Finally, the DR strategy has been applied to investigate the asymmetries induced by jet cooling of turbine blades.

Project objectives

Los objetivos perseguidos en esta aportación se centran en mejorar la eficiencia y aplicabilidad del análisis de estabilidad en flujos aerodinámicos complejos mediante la estrategia de reducción de dominio. Se pretende analizar la estrategia de reducción de dominio para evaluar su impacto en la precisión de los modos propios recuperados. Además, se busca proporcionar una herramienta de estimación de error que permita cuantificar la exactitud de los resultados obtenidos. También se aspira a estudiar la aplicabilidad y limitaciones de esta metodología en problemas específicos, como el flujo en cavidades abiertas. Finalmente, se pretende explotar la herramienta de estimación en fenómenos transónicos y aplicar la estrategia para investigar asimetrías inducidas por el enfriamiento por chorro en álabes de turbina.
