    Computation of Aerodynamic Damping for Flutter Analysis of a Transonic Fan

    No full text
    This paper describes the computational analysis of aerodynamic damping for prediction of flutter characteristics of a transonic fan stage that consists of a highly loaded rotor along with a tandem stator. Three dimensional, linearized Navier-Stokes flow solver TRACE is used to numerically analyse the flutter stability of the fan. The linear flow solver enables the modeling of a single blade passage to simulate the desired inter-blade phase angle. The unsteady aerodynamic load on a vibrating blade is obtained by solving the unsteady Navier-Stokes equations on a dynamically deforming grid and the energy exchange method is used to calculate the aerodynamic damping. The calculation of aerodynamic damping for the prediction of flutter characteristics of the fan rotor is carried out with and without considering the influence of the disk. The blade mode shapes from finite element modal analysis are obtained accordingly and the flutter calculations are carried out for three blade vibration modes at the design speed and at part speeds for all possible inter-blade phase angles. Two operating points, one on the working line and the other near stall are investigated at every rotational speed. Different aspects that affect the aerodynamic damping behaviour like part speed operation, variation in unsteady blade surface pressure fluctuation between operating points on the working line and at near stall and the corresponding variation in aerodynamic work, inter-blade phase angle etc., are described. This analysis primarily focuses on the variations in aerodynamic damping of the fan with and without the influence of the disk. In addition, influence and effect of shock wave on the aerodynamic damping is also discussed

    Going beyond on-pitch success: fan engagement as a catalyst for growth

    No full text
    This research investigates the case of fan engagement as a strategy for long-term growth for football clubs. Through an exploratory methodology this study gains a valuable insight into the current perceptions and usage of fan engagement, with a particular focus on social media. Whilst the subject of social media is growing in academic journals, there is very little understanding of how sport organisations are using this platform. 14 semi-structured interviews with key industry personnel and a fan focus group in addition to a content analysis of the Twitter feeds of 10 Premier League football clubs was undertaken to offer new insight to the academic conversation in this subject area. The research findings suggest that clubs need to develop ways to build and create long-term loyalty through fan engagement in preference to unsustainable growth strategies based exclusively on winning and on-pitch performance. Since winning is only possible for a select few every season, a strategy that places the fan at the centre of the club will prove beneficial to most clubs at all levels in the long term. With the incoming financial controls being implemented across the English football leagues in addition to UEFA’s Financial Fair Play legislation, the significance of developing long-term profitability has never been more evident. Those clubs which place Customer Relationship Management (CRM) as an overriding philosophy throughout the organisation and develop social media platforms effectively as part of a CRM strategy are best placed to improve their understanding of fans and adapt their marketing strategies to build loyalty and advocacy to the brand, which in time will deliver profitability and long-term growth
