Outline of Final Research Achievements |
The research proposed a practical and accurate method for wake flow measurement which was important to improve the aerodynamic performance of transport planes and vehicles. The method is the combination of stereo-PIV measurement and mathematical equations to be solved using a computer. In general, some instruments are needed to measure flow-field quantities, while the instruments could violate the flow-field, then accuracy could not be guaranteed. The proposed method is nonintrusive and productive, that is an advantage for measurement. Its originality lies in a basic equation called the 2.5-dimensional model to compute pressure quantities as well as large scaled stereo-PIV experiment to obtain velocity vector components. It was shown the proposed method had good ability of providing accurate physical properties such as velocity vectors and pressure when several boundaries were located on the isentropic flow region and the Neumann boundary conditions held for other boundaries.
