Eirik Æsøy
About
My main research interest is understanding and controlling the interactions between different types of flow, e.g. flow around bodies and acoustics waves or currents and free surface waves.
Research Areas
Combustion dynamics: Interactions between flow, acoustics, and flames that lead to self-induced instabilities in combustion applications.
Flow dynamics and control: Manipulating the interactions between instabilities for control applications.
Free surface and multiphase flows: Interactions between currents and free surface waves, and multiphase flow in pipes.
