STOCHASTIC MODELING OF LAMINAR-TURBULENT TRANSITION

R. Rubinstein, M. Choudhari
NASA Langley Research Center, USA

Keywords: turbulence, transition, parabolized stability equations, resonant triads

Stochastic versions of stability equations are proposed as a basis for integrated modeling of transition and turbulence and for understanding the effects of uncertain initial conditions on disturbance growth. Stochastic forms of the resonant triad equations, a high Reynolds number asympotitc theory, and the parabolized stability equations are considered.
