The effects of differential diffusion for burning turbulent velocity of NH3/H2/Air mixtures for flames spherical

A combustion chamber experiment with Ammonia gas and Hydrogen to investigate turbulence combustion. The experiment used high-speed impellers to swirl the combustion chamber, resulting in turbulent combustion conditions. The fan-stirred bomb was used to measure the turbulent flame speeds of fuels. The growth of the flame under constant pressure was shown using Schlieren photography. The MATLAB program code was used to process and analyze the images obtained by the Schlieren system. Flame acceleration caused the flame speeds to increase with radius. Levels of effective turbulence intensity were calculated and found to rise gradually with flame radius. The experiment began at 100, 200, and 300 kPa, with equivalency ratios of 0.8, 1, and 1.3, respectively. When the conditions were changed to have the same equivalency ratio and different starting pressures, or the same initial pressure but different equivalency ratios, the calculated turbulent combustion speed was obtained. By increasing combustion efficiency, turbulence accelerates combustion. This experiment shows that turbulence increases combustion speed, which leads to more efficient burning of fuel combinations. The design and results of this study advance our knowledge of combustion processes and might lead to increased combustion efficiency in a range of applications, such as furnaces and engines.
