Simulation of the Vulcain engine oxygen-hydrogen injectors thanks to liquid helium.

Simulation des injecteurs oxygène-hydrogène du moteur Vulcain par de l'hélium liquide.

Author(s) : PUECH L., LADAM Y., WOLF P. E., et al.

Summary

Within the framework of the "Combustion dans les moteurs de fusée" (Combustion in rocket engines) research group, the "Centre de recherche sur les très basses températures (Centre for research on ultra-low temperatures)" has performed a modelling experiment, in which the fractionation of liquid oxygen into droplets and its evaporation can be studied. This simulation closely resembles real cases, but in the absence of any combustion. Thanks to the optical properties of helium, it was possible to quantify the effects of vaporization in the densely foggy areas in which traditional granulometric methods can not operate. After a brief presentation of the physical problems raised by these types of injectors, the advantages of using optical methods for helium are described.
