Clean combustion such as hydrogen for the reduction of NOx emission is prone to thermoacoustic instabilities, which may cause structural vibrations and equipment failures. In present work, an adjoint-based sensitivity analysis applied a low-order model with non-zero mean flow. The can be powerful tool yield information optimization techniques eliminate or control instabilities. With quick low-cost calculations, base-state are achieved conditions most sensitive instabilities identified.
