Wavelet-based resolvent analysis of non-stationary flows
Eric Ballouz, Barbara Lopez-Doriga, Scott T. M. Dawson +1
This work introduces a formulation of resolvent analysis that uses wavelet transforms rather than Fourier transforms in time. Under this formulation, resolvent analysis may extend…
Sparse space-time resolvent analysis for statistically-stationary and time-varying flows
Barbara Lopez-Doriga, Eric Ballouz, H. Jane Bae +1
Resolvent analysis provides a framework to predict coherent spatio-temporal structures of largest linear energy amplification, through a singular value decomposition (SVD) of the r…
Are the dynamics of wall turbulence in minimal channels and larger domain channels equivalent? A graph-theoretic approach
Ahmed Elnahhas, Emma Lenz, Parviz Moin +2
This work proposes two algorithmic approaches to extract critical dynamical mechanisms in wall-bounded turbulence with minimum human bias. In both approaches, multiple types of coh…
Linear and nonlinear Granger causality analysis of turbulent duct flows
Barbara Lopez-Doriga, Marco Atzori, Ricardo Vinuesa +3
This research focuses on the identification and causality analysis of coherent structures that arise in turbulent flows in square and rectangular ducts. Coherent structures are fir…
