摘要

In this research, “Data Assimilation” was applied to a wind tunnel experiment. A square cylinder wind tunnel experiment and the ensemble Kalman filter were used to integrate surface pressures of a square cylinder obtained from computation and experiment. The results indicated that surface pressures of the square cylinder and flow field can be replicated by the present data assimilation method, while they could not be replicated by numerical simulation alone. The results of the ensemble Kalman filter were compared with those of “Measurement-Integrated Simulation,” which is another integrated method between computation and experiment for fluids.
