We consider long-time simulations of two-dimensional turbulence body forced by sin 4yˆx on the torus (x, y) ∈ [0, 2π] 2 with the purpose of extracting simple invariant sets or 'exact recurrent flows' embedded in this turbulence. Each recurrent flow represents a sustained closed cycle of dynamical processes which underpins the turbulence. These are used to(More)
This paper describes a derivation of the adjoint low Mach number equations and their implementation and validation within a global mode solver. The advantage of using the low Mach number equations and their adjoints is that they are appropriate for flows with variable density, such as flames, but do not require resolution of acoustic waves. Two versions of(More)
