Introduction to Hydrogen fuelled scramjet combustor

The scramjet  engine  is one of the most  promising propulsive systems for future hypersonic vehicles.   Over  the  last  fifty  years   the  scramjet   engine   technology  has  been  intensively investigated and  several  such engines have  been flight-tested in recent  years  (Neal, Michael, &  Allan,  2005; Paul,  Vincent,   Luat,  &  Jeryl,  2004).  Research   on  supersonic combustion technologies is of great  significance for the design of the engine  and  many  researchers pay significant attention to  the  hypersonic airbreathing propulsion. The  mixing  and  diffusive combustion of fuel and  air in conventional scramjet  engines take place simultaneously in the combustor (Huang, Qin, Luo, & Wang, 2010). Since the incoming supersonic flow can stay in the  combustor only  for a very  short  period of time,  i.e. of the  order of milliseconds (Aso, Inoue,  Yamaguchi, & Tani, 2009; Huang et al., 2010; Hyungseok, Hui,  Jaewoo,  & Yunghwan,…
