Lagrangian Analysis



  • Massless tracers follow the flow pathlines

  • This property allows analyzing different flow configurations     

  • The technique is known as Lagrangian Analysis

  • Can provide unique insights for turbulent flames and detonations 

Research Details

  • Advection of tracers requires accurate numerical algorithms

  • Especially important for highly compressible turbulent flows

  • Development of accurate time integration and interpolation methods 

  • WENO-based interpolation for highly compressible regimes
