The study characterizes the behavior of a premixed swirl stabilized dump plane combustor flame near its lean blow-out (LBO) limit in terms of CH* chemiluminiscence intensity and observable flame color variations for a wide range of equivalence ratio, flow rates and degree of premixing (characterized by premixing length, L fuel ). LPG and pure methane are used as fuel. We propose a novel LBO prediction strategy based solely on the flame color. It is observed that as the flame approaches LBO, its color changes from reddish to blue. This observation is found to be valid for different levels of fuel-air premixing achieved by changing the available mixing length of the air and the fuel upstream of the dump plane although the flame dynamics were significantly different. Based on this observation, the ratio of the intensities of red and blue components of the flame as captured by a color CCD camera was used as a metric for detecting the proximity of the flame to LBO. Tests were carried out for a wide range of air flow rates and using LPG and CH 4 as fuel. For all the operating conditions and both fuels tested, this ratio was found to monotonically decrease as LBO was approached. Moreover, the value of this ratio was within a small range close to LBO for all the cases investigated. This makes the ratio suitable as a metric for LBO detection at all levels of premixing.

“…Scholars (e.g. Rolfe, 2003;Rowley, Lujan and Dolence, 1997;Shattock, 2000;de Zilwa, 2010) have explained this development by reference to external factors, such as reduced public funding, the pressures for internationalisation, newly available teaching and other technologies, increased accountability to stakeholders, and the widespread use of rankings. In the context of Finnish universities, from where the empirical material of this article originates, the adaptation of strategic management is strongly associated with the latest phase of national university reform, namely the legislative change that addresses a clear shift of decision making authority from the state to the universities (Tirronen, 2014).…”

This study examines university strategies from the content perspective. Since the early 1980s, the pressure to adopt strategic management in universities and other higher education institutions has increased because of issues including reduced public funding, pressures and possibilities for internationalisation, developments in teaching technologies, and demands for increased accountability to stakeholders. The study employs content analysis and multivariate statistical techniques to examine the written strategies of 13 Finnish universities formulated after the University Act 2010 that aimed at enhancing their competitiveness in the global arena. The studied organisations cover practically Finland's entire university sector. As a novel tool, the study introduces visual presentations of strategy and investigates to what degree the strategies conform to general content strategy frameworks, such as generic competitive strategies, strategic types, and value disciplines. The results indicate only light conformity with such frameworks. Finally, the study discusses the implications of these findings for both researchers and practitioners of management in the higher education sector.
