TOPICS:
- Turbulence: moment of momentum conservation;
large eddy simulation: sub-grid modeling, variable scale filtering and
structure of the noncommutating filltered equations, noncommutation procedure;
DNS and LES of shearless decaying mixings.
- Thin
shear flows: laminar two-dimensional bluff body wake: boundary layer asympotic
expansion solution, NS matched asymptotic expansions for the intermediate and
far flow, linear nonparallel instability
- Compressible
turbulent flow, astrophysical applications - application of the Kolmogorof
theory to astrophysical accretion models; laboratory simulation of hypersonic
jets by varying the ambient/ jet density ratio, partial similitude (Mach,
density ratio) - for stellar jets.
