Velocity, temperature, and electric field measurements on a plasma-assisted hydrogen diffusion flame (2018-11-08)A plasma-assisted hydrogen diffusion flame, denoted as a coaxial AC DBD burner, was designed and analyzed for comparisons with simulations and to better understand the coupling of the plasma and reacting flow. Emission, ...
