内容記述 | Measurement Integrated Simulation (MIS) is a data assimilation method using the idea of a flow observer. MIS is already used in the analysis of incompressible fluids in biomedical and pipe flows. In this study, a coupled system of a CFD solver and an MIS algorithm was constructed, and an identical twin experiment for the flow field around a 2-dimensional airfoil subject to different boundary conditions was performed. It was found that the MIS reproduced the aerodynamic coefficients of target data even if different boundary conditions are set. The accuracy of MIS was demonstrated, not only for the physical properties used for the assimilation but also for unassimilated properties. In addition, for sample data with random or bias error, the difference between the simulated and sample data achieved by the computation with MIS was much smaller than the difference achieved without MIS. | |||||
