| Outline of Final Research Achievements |
The purpose of the study was to propose a new numerical method which could enable evaluation of the second velocity component (v) on x-y plane in the case where a profile of the first component (u) was given. Derivatives in the out-of-plane (z) direction in the governing equations should be considered so that 3-dimensional characteristics of the flow could be reflected on the calculated flow field. In the proposed method, not only the two velocity components but also divergence and vorticity were expressed by the Fourier series expansion, and it was assumed that the Fourier coefficients for divergence and vorticity were equal. Although the quantitative performance of the present method is not always satisfactory, the positions of flow suction (negative divergence) and flow source (positive divergence) were well-predicted by the present method. It can be concluded that the present method has good potential to calculate a reasonable velocity profile.
