“Fazoperehod’ (“Phase Transition”) Space Experiment

“Fazoperehod’ (“Phase Transition”) Space Experiment is run on board the “Progress-M” cargo transport vehicle being a part of the ISS. The purpose of “Fazoperehod” is to determine performance specifications of heat pipes in the orbital operational environment. Heat pipes themselves are components of heat transfer elements (HTE), which also include electric heater blocks (installed on the evaporative sec-tion of heat pipes) and a radiator (installed on the condenser section). The HTEs are mounted in pairs on three platforms located at the external lateral surface of the Progdivess spacecraft.

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.
