摘要
Abstract
In the pursuit of a carbon-neutral society,hydrogen,as a zero-carbon fuel,has gained significant attention in aviation propulsion systems.Hydrogen has a higher flame propagation speed and a thinner flame thickness,which increases the risk of flashback in the design and operation of hydrogen-fueled combustor.The widely used micro-mixer nozzle effectively prevents core flow flashback by increasing axial velocity.However,the boundary layer flashback re-mains a challenging issue in the hydrogen-fueled combustor.This paper gives a review of the research on the bound-ary layer flashback of hydrogen-fueled combustor.The flame propagation characteristics and unique molecular trans-port properties of hydrogen are examined.Experimental and numerical simulations for non-swirling and swirling bound-ary layer flashback are reviewed.The flashback criteria on the laminar and turbulent boundary layer developed over re-cent decades are summarized.The fast flashback prediction method is introduced.Current challenges in the research on boundary layer flashback in hydrogen-fueled combustors,and the future development of boundary layer flashback criterion and modeling for premixed hydrogen flames is also discussed.关键词
