Сylinder Replacement for Experiment Difusion Flame

Experiment Difusion Flame

Objective:

Obtaining high-precision experimental data for studying laminar diffusion flame in the concurrent stream of fuel and oxidizer.

Tasks:

• Experimental study of the properties of diffusion flame of methane and ethane in the concurrent stream of air under microgravity conditions. Obtaining data about the shape of the flame, the height at which the ‘suspended’ flame stabilizes, its temperature, soot formation and the limits of its existence depending on the flow rate and the mixture dilution. Obtaining data about soot-forming diffusion flame by changing the shape of the flame, the temperature of the gas in the soot-free area of the flame, soot luminosity, soot temperature and volumetric ratio of soot particles depending on the flow rate and the mixture dilution.
• Development of procedures for analyzing experimental data on the basis of theoretical calculations of characteristics and structure of the diffusion flame under microgravity conditions and comparing analytical data with those obtained in the course of space experiment.
• Providing scientifically proven recommendations on changing the modes of carrying out the space experiment.
• Obtaining and processing experimental data, solving a number of inverse problems to extract kinetic data for detailed and reduced models of diffusion flame under microgravity conditions.
