Abstract: The objective of the current research is the experimental investigation of the pulsating flow effects on the combustion performance in terms of the flame temperature distribution, the heat transfer rate, the combustion efficiency and the exhaust gas analysis. The flow pulsation provided through a rotary ball valve in accordance with a variable speed motor arrangement increased the flame temperature fluctuation and the magnitude of heat release. The flow pulsation provides a highly turbulent flame wherein the vortices are enlarged. Increasing Strouhal number [St] of the LPG fuel and air flow increases the time-averaged flame temperature of the pulsating flame up to a saturation level that is dictated by the heat transfer rate enhancement. The maximum average flame temperature is 1263oC at St= 0.041, r= 0 mm and 100 mm from the burner inlet. In addition, increasing the pulsating flow amplitude increases the convection and radiation heat fluxes from the pulsating flame. While increasing the pulsation decreases the exhaust UHC due to increasing the turbulent kinetic energy across the pulsating flame, the exhaust NOx slightly increases due to increasing the heat release rate and the flame temperatures. Pulsation thus enhances the combustion efficiency inside the industrial combustors. 
Keywords: External pulsation, pulsating flame, Inlet flame port, Diffusion flame, Pulsation frequency, pulsator combustor.

Abstract: This paper takes a close look at the relevance of Bourdieu’s concepts of habitus, field and capital in enhancing learning in engineering education andproposes that effective engineering education can be achieved through the adoption of appropriate measures related to Bourdieu’s theories.it further shows the link between the concepts of field, capital and habitus and explores how engineering institutions can restructureteaching methods and curriculum content in a way that students can relate and respond to. This paper also highlights environmental and foundational changes that need to be imbibed from the elementary stages of education to help mould a potential teacher to be effective in the field and build capital that further impacts his effectiveness as a teacher. Again, through the review of related literature, this study explores how academia’s habitus affects their teaching methods within the field and the effect of institutional systems and environment on the pedagogy of engineering educators. The study further outlines some of the challenges limiting the field of engineering education stemming from deficiencies from an individuals past and current environment, followed by a description of key initiatives and recommendations aimed at better pedagogy and learning techniques for productive ngineering education.
