Swirl-Stabilised Hydrogen Combustor with Axial Air Injection: Numerical Simulations and Cold Flow Experiments

Swirl-stabilised hydrogen combustion has great potential in the aviation industry since emissions can be significantly reduced compared to fossil fuels. However, a major drawback is a high proneness to flashback. This could be overcome with non-swirling axial air injection (AAI) on the centre-line of the mixing tube. The effect of this concept...
