Nonlinear estimation in turbulent channel flows

Jitong Ding, Simon J. Illingworth

We design a nonlinear estimator for channel flows at $R e_{I ¨} = 180$ and $590$ . The nonlinear estimator uses a linear estimator structure based on the linearised Navier-Stokes equation…

Mode-to-mode nonlinear energy transfer in turbulent channel flows

Jitong Ding, Daniel Chung, Simon J. Illingworth

We investigate nonlinear energy transfer for channel flows at friction Reynolds numbers of $R e_{I ¨} = 180$ and $590$ . The key feature of the analysis is that we introduce a new variabl…
