Experimental verification of optical analog of heated molecular gas jets

Confirmed measurements of gasodynamic and optical features of subsonic flooded turbulent jets heated up to 850 K are carried out. It is shown, that fields of energy brightness spectral density and radiation power within frequencies, where radiation is of volume character, are described using universal function, where combination of flowing-away initial parameters represents the scale, while dimensionless variables, where flowing is self-model, represent - independent variable. Conclusion is made, that distribution of spectral density of energy brightness and total intensity of radiation of subsonic filled jets depend on flowing-away conditions: initial temperature, concentration of emitting component, radius of gas conduit, as well, degree of overheating and initial degree of flow-turbulence. On the basis of the obtained data one realizes optical technique of jet flow diagnostics.
