Embodiments of the present disclosure include an injection system. The injection system includes a Resonance Enhanced Microjet (REM) nozzle. The REM nozzles includes a REM nozzle block, the REM nozzle block having an inlet formed in a top and an outlet formed in a bottom, the inlet and outlet being fluid coupled together. The REM nozzle also includes one or more micronozzles positioned about the outlet, the one or more micronozzles having an outlet and being positioned at an angle relative to the bottom. Additionally, the REM nozzle includes an inlet conduit coupled to the REM nozzle block, the inlet conduit being fluidly coupled to the one or more micronozzles. The injection system also includes a source arranged proximate the top, the source directing a source jet of fluid into the inlet. The injection system includes a fuel supply fluidly coupled to the inlet conduit. Such a system can inject a fuel entrained in an oxidizer pulsing at very high-frequency. These pulsed fuel-oxidizer streams can be injected to a high-velocity fluid stream which allows better mixing of fuel and oxidizer at high speed.
