| Outline of Final Research Achievements |
Feasibility study of optimal measurement based on data assimilation was conducted by connecting a supercomputer and a wind tunnel in real-time. In the experiment, the wake of a model was measured by a Pitot tube, which is supported by a three-dimensional traverse system. Processing of measurement data, control of the traverse system, and data transfer to the supercomputer were carried out by the LabVIEW software installed on a PC. Numerical flow analysis is conducted during the measurement on the supercomputer so that the sensitivity of additional measurements to a cost function can be obtained and the information is fed back to the LabVIEW PC to locate new measurement positions. Numerical costs of flow prediction and sensitivity analysis were reduced by using a reduced-order model based on a radial basis function. We also introduced the AVS software with the augmented realization (AR) module which enables to superimpose images of numerical results on the view of the experiment.
