Emergence of order from chaos in turbulent systems and Bose-Einstein condensation

This ordering leads to aeroelastic flutter and thermoacoustic instabilities as observed during the failure of the F1 engine of Apollo rocket during trials
An important phenomenon studied in aerospace engineering is the emergence of order from chaos in turbulent systems that leads to detrimental large amplitude fluctuations. Examples of this include aeroelastic flutter as observed in the wings of aircraft and thermoacoustic instabilities in rocket combustors, both of which can lead to the breaking down of the system. For this reason, it is important to be able to predict and understand such happenings and avoid them. At R.I. Sujith’s lab in the Department of Aerospace Engineering of IIT Madras, this phenomenon has been studied for years. As he succinctly explains: Thermoacoustic instability, which comprises self-sustained large amplitude periodic oscillations, can overwhelm the thermal protection system in combustion chambers, cause damage to structural parts such as turbine blades, or even affect the guidance and control system of rockets and lead to mission failures.More Related News
