  4. 3. Investigating the Impact of Water Injection on Noise Generation During Rocket Lift-Off

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Sångberg Linus; [2021]
    Keywords : Rocket lift-off; Turbulent mixing noise; CFD;

    Abstract : This thesis aim to provide SSC, Swedish Space Corporation, with a foundation for understanding the key ideas behind water injection during rocket lift-off, including problems to be avoided when simulating the phenomena. This investigation focus on finding approaches suitable for obtaining a rough estimate of the reduction in noise generation, when too expensive equipment required is absent. READ MORE
