Hydrogen fuel injected into a scramjet combustor must mix rapidly if complete combustion is to occur within a reasonable stream wise distance. An experiment has been conducted to determine whether the addition of swirl will improve the mixing of a supersonic jet of fuel simulant (helium or air) injected at 30 deg to the wall into a confined Mach 2 airflow. The swirling jets were created by injecting the fuel simulant tangentially into a cylindrical chamber and accelerating it through a… CONTINUE READING
