A systems perspective on non-normality in low-order thermoacoustic models: Full norms, semi-norms and transient growth

Non-normal transient growth of energy is a feature encountered in many physical systems. Its observation is intimately related to the norm used to describe the system dynamics. For a multi-physics problem such as thermoacoustics, where a heat source is in feedback with acoustic waves and a flow fiel...
