Stretching and folding diagnostics in solutions of the three-dimensional Euler and Navier-Stokes equations
diagnostics three-dimensional Euler Navier-Stokes equations
2011/3/3
Two possible diagnostics of stretching and folding (S&F) in fluid flows are discussed, based on the dynamics of the gradient of potential vor-ticity (q = ω · ∇) associated with solutions of the...
