内容記述 | In this study, the pressure estimation system was developed to enhance the value of PIV (Particle Image Velocimetry) measurement technique. The system conducts CFD (Computational Fluid Dynamics) computation to estimate pressure using PIV velocity data. The Poisson equation for pressure is the basic equation for the computation. After developing the CFD, the pressure estimation system was verified by using Navier-Stokes simulation results. Instead of PIV data, the velocity data of the simulation results were used as input data, and pressure values were calculated by the system. Then, the calculated pressure values were compared with those resulted by the Navier-Stokes simulation. After the validation check, pressure estimation using experimental data was done. The experimental data came from the experiment of wake measurement of a cranked arrow wing in JAXA's low-speed wind tunnel. Moreover, the influence of the measurement error to the system was evaluated. The evaluation can predict the correlation between measurement errors in velocity data and errors in estimated pressure values. The artificially generate errors were distributed over the original input velocity data. Then, analysis was done comparing pressure values obtained without the error and those with the error. It was found that input error magnitude reduced on the calculated pressure value. | |||||
