Cardiff University Gas Turbine Research Centre Pressurised Counter Flow Burner commissioning going well, with the first data set taken for methane at atmospheric pressure and temperature. This video shows the flat flame which establishes along the stagnation plane between the opposing jets.
Premixed CH4-Air Counterflow Flame
In this configuration we have premixed air and methane flowing from the bottom nozzle, and nitrogen from the top nozzle. Increasing the velocity of the opposing jets allows fundamental measurements of extinction strain rate to be made. This is critical for engineers to understand changes in zero-carbon fuel behaviour, and facilitates the design of next generation combustors.
