4D large scale variational data assimilation of a turbulent flow with a dynamics error model

P Chandramouli, E Memin, D Heitz - Journal of Computational Physics, 2020 - Elsevier
We present a variational assimilation technique (4D-Var) to reconstruct time resolved
incompressible turbulent flows from measurements on two orthogonal 2D planes. The …
