The algorithm is applied to the flow around a two-dimensional, wall-mounted, square prism. To reduce the problem dimensionality, snapshots of flow and scalar fields are processed to derive POD modes and their time coefficients. Then a system identification algorithm is employed to build a reduced order, linear, dynamical system for the flow and scalar dynamics. Optimal estimation theory is subsequently applied to derive a Kalman estimator to predict the time coefficients of the POD modes from sparse measurements. Analysis of the flow and scalar spectra demonstrate that the flow field leaves its footprint on the scalar, thus extracting velocity from scalar concentration measurements is meaningful. 2023-04-17T09:13:43Z 2023-04-17T09:13:43Z 2023 Book https://link.springer.com/article/10.1007/s10494-023-00417-2 https://dlib.phenikaa-uni.edu.vn/handle/PNK/8008 en application/pdf Springer
