Abstract

In the scope of the french national project DRIVE and european project HyPER, high pressure jet flame of hydrogen were produced and instrumented.

The experimental technique and measurement strategy will be presented. Many points are original developments like the direct measurement of the mass flowrate by weighing continuously the hydrogen container, the imaging processing to extract the flame geometry, the heat flux measurement device, the thermocouples...

Flame have been produced from 900 bar down to 1 bar through orifices ranging from 1 to 10 mm. Thus an original set of data is now available not only about the flame but also about the thermodynamic properties of high pressure hydrogen (since the pressure and the temperature in the container were continously monitored during the release).

A comparison with other published data is proposed and a discussion of some available models
