To stall-cell or not to stall-cell: Variational data assimilation of 3D mean flow past a stalled airfoil
Uttam Cadambi Padmanaban, Craig Thompson, Bharathram Ganapathisubramani +1
The full-field reconstruction of three-dimensional (3D) turbulent flows from sparse experimental measurements remains a significant challenge, particularly for flows exhibiting com…

Assimilating rough features: A data-driven framework to infer rough wall properties from sparse experimental data
Martina Formichetti, Uttam Cadambi Padmanaban, Ping He +2
Surface roughness influences turbulent boundary layers (TBLs) primarily through the roughness function and the equivalent sand-grain roughness height \(k_s\). Direct determi…
