Understanding the dynamics and the stabilisation of flames is important for practical applications and for theoretical research. Here, to investigate the time-evolution of a Bunsen flame in a Poiseuille flow, we extend a G-equation-based kinematic model by accounting for flame stabilisation. The nonlinear G-equation is solved analytically using the methods of characteristics. The solution is th...

The study objective is to investigate the combustion characteristics of Callophyllum inophyllum fuel in presence a magnetic fields. To conduct experiment, bunsen burner was utilized, with and air being dispensed via syringe pump compressor, both regulated by flowmeter. pipes were heated 532.15 (K) facilitate evaporation. equivalent ratio 0.5, 1, 1.5 adjusted control discharge fuel. An 11,000 ga...

Ammonia as a fuel has sparked significant interest in the combustion community. Although, using ammonia lot of advantages including no carbon emissions, ammonia-air flames are characterized thick with low flame speeds. It is important to understand structure know process better. Flame thickness an property which characterizes reactivity flame. Identifying preheat zone necessary determine fresh ...

This article is a report of the attempts which were made to model an industrial premix gas burner which was operating in one of the furnaces of the Catalytic Reforming Unit (CRU) of Abadan refinery. The main objective of the modeling was to investigate on the effect of the structural geometry of the burner on its mode of operation, i. e. complete combustion of the gas, maximum generation of hea...

Atomic hydrogen (H) and hydroxyl radical (OH) are two key intermediate species in the combustion of hydrocarbon fuels. For example, spatial temporal distribution H is useful to better understand ignition/extinction processes, whereas OH profiles can yield flame structure reaction zone different flames conditions. In present study, simultaneous laser-induced fluorescence (LIF) measurements obtai...

An experimental and numerical investigation on the effect of swirl on the motion of coal particles in the near-burner region of a versatile multi-fuel swirl-stabilised laboratory burner of total thermal input of 100kW, has been performed. The burner was designed as a scale model of a lOMW coal burner operating in a cement rotary kiln, produces flames of different aerodynamic characteristics, an...
