“…It consists of a single fuel injector element that injects fuel into the airflow. While simple in design, it may suffer from challenges such as uneven fuel distribution and limited control over the fuel–air mixing process 14 – 16 . However, it is a cost-effective solution that can be used in certain operating conditions 17 .…”

The main attention of this work is to investigate the usage of diamond multi extruded injectors on the fuel distribution in combustor of scramjet. This study applied the computational technique to simulate the transverse fuel jets released from extruded nozzles. The main focus is to evaluate the role of induced shock waves on the penetration and distribution of fuel jets. The effects of jet space and usage of annular nozzle for the fuel injection system are revealed. Results of this work shows that the gap of jet would be more efficient for mixing when the inner air jet is also used. Also, injection of the air from the core of annular nozzle significantly increase the fuel mixing.
