- Dr. Qi Wang's research exploits state-of-the-art mathematical and computational methods
to address important challenges in turbulence. High-performance simulation techniques
are developed and adopted to predict and optimize complex aerodynamic flows, and to
optimally place sensors
and optimize the interpretation of their measurements.
- Dr. Wang's past research helped to answer this question by exploiting the discrete
adjoint operator in different scenarios: passive scalar source reconstruction and
localization from noisy sensor measurement, initial flow state reconstruction from
wall friction measurements, sensitivity analysis for transitional compressible boundary
layer, and data augmentation in stratified flows.
