Mitigating adjoint chaos in wall turbulence
Qi Wang, Tamer A. Zaki
Estimating past events in wall turbulence based solely on surface measurements and first principles is an ill-posed problem that is complicated by chaos. The sensitivity of a measu…

Latent-space variational data assimilation in two-dimensional turbulence
Andrew Cleary, Qi Wang, Tamer A. Zaki
Starting from limited measurements of a turbulent flow, data assimilation (DA) attempts to estimate all the spatio-temporal scales of motion. Success is dependent on whether the sy…
