Abstract:In the past two decades, the level set concept has been extensively explored. The superiority of the differential level set to other more ad hoc methods as a formal framework for directly/indirectly solving ‘front-propagation’ natured problems is now fully established. Nowadays, in many areas of aerospace related computational fluid dynamics, applications of level set methods can be found. This paper gives a brief review of these applications and how level sets can be useful in tackling challenging computational aerospace problems. The use of level sets in premixed turbulent combustion, aero-acoustics, geometry definition/morphing, meshing and turbulence modeling is explored in detail and other applications discussed.
