    Turbulence generation and induction within a deflagrated flame has been identified as a key mechanism for flame acceleration to detonation. The current state-of-the-art technique to achieve this mechanism is through the use of solid obstacles. These obstacles obstruct the flow and induce turbulent combustion with the goal of achieving detonation. However, these obstacles have drawbacks such as pressure losses, heat absorption, and weight addition. An innovative method for inducing turbulence that eliminates these disadvantages is with the use of fluidic jets. The study explores the deflagrated flame augmentation using a fluidic jet. The research identifies the key mechanisms of the interaction between a turbulent deflagrated flame and a turbulent jet in crossflow. Another focus of the study is to classify the effect of the initial flame regime on flame acceleration by comparing the flow development of a turbulent flame to that of a laminar flame. Advanced high-speed particle image velocimetry (PIV) and Schlieren imaging are used to analyze the physics of the interaction and flame acceleration
