Laminar Propagation of Lean-Premixed Flames in Meso-scale Tubes
Abstract: A meso-scale channel was earlier developed [1] for the propagation of laminar lean premixed flames. This paper, therefore, reports the experimental variations of flame speed with inner meso-scale tube diameters (di), equivalence ratio (φ), and mixture flow rate (Q) with methane and propane fuels using the meso-scale channel developed earlier. Based on the flame front history, flame speed (SL) and propagation speed (Ud) were computed at temperature (T) greater than …

Experimental investigation on non-linearity in understanding large scale fires
Abstract: Fire doesn't spread in a uniform manner it has an unpredictable nature. The pervasive uncertainty associated with large-scale fires has resulted in the irreparable loss of invaluable human lives, natural resources, critical infrastructure, and systems. To combat this significant issue, substantial financial investments are made annually in research endeavours aimed at preventing and mitigating such devastating incidents. These dedicated research efforts strive to develop innovative strategies, cutting-edge technologies, and robust …

Laser stimulated downward combustion propagation phenomenon
Abstract: Enhanced energy requirement has necessitated active research efforts to understand combustion behaviour in presence of alternative energy sources. In the last five decades, emphasis on combustion focuses on two aspects viz., improving quality of combustion and addressing the risks/hazards. With recent advancement, an aspect which is researched upon is the combustion behaviour in the presence of laser flow. Their applications pertain to propulsion, energy generation, artillery, fire safety and defence …

Flame Phenomenology for Premixed Methane and Propane/Air in Developed Meso-scale Channels at Ambient Conditions
Abstract: This paper reports the development of a meso-scale channel for propagation of methane and propane-air mixtures at low Reynolds number. An experiment was conducted in 3, 4 and 5 mm internal quartz tube diameters at premixed conditions of the fuel/air. The tubes were vertically mounted and sometimes preheated uniformly laterally. Uniformly laterally heating gives a zero temperature gradient. Flame phenomenology at different equivalence ratios (φ) of the mixture was discussed. …
