特集1 : 研究解説 : Turbulence Models for Practical Applications Part 4 : Examples of Model Applications for 2D Separated Flows

Examples are presented of calculations performed with the relatively simple turbulence models surveyed in the first half of the paper (Part1, 2). The examples cover a wide range of engineering and environmental flows and are subdivided into two-dimensional thin-shear-layer flows, two-dimensional separated flows and threedimensional flows. In Part4, calculated results of two-dimensional separated flows are presented and the quality of the calculated results is assessed by comparison with measurements. The paper focusses on applications of the k-ε turbulence model and its variants, but, when available, results obtained with other models are included for comparison特集 乱流の数値シミュレーション（NST） その
