        abstract = {Scramjet engines are advanced air-breathing propulsion systems designed for hypersonic flight above Mach 5. Stable and efficient combustion is challenging because the airflow remains supersonic and the available residence time is extremely short.
The supplied analyzes velocity, pressure, temperature and turbulence fields using CFD. The PI controller monitors combustor temperature and adjusts hydrogen fuel mass flow to maintain a desired setpoint. Reported results indicate that higher-TKE regions promote fuel-air mixing and combustion efficiency, while PI-based fuel-flow control reduces temperature fluctuations and improves stability.
The supplied study investigates turbulent kinetic energy (TKE) in a hydrogen-fueled scramjet combustor using Computational Fluid Dynamics. Velocity, pressure, temperature and turbulence fields are analyzed to understand fuel-air mixing and combustion stability.
A closed-loop Proportional-Integral controller regulates hydrogen fuel mass flow using combustor temperature feedback. The reported results indicate that higher-TKE regions promote mixing and combustion efficiency, while PI control reduces temperature fluctuations.
