          <datacite:description descriptionType="Abstract">2次元噴流の衝突について流体の粘性を考慮した解析に着手する前に複素ポテンシャルによる解を流体力学的な意味で調べた。この解は粘性解析でレイノルズ数を増加した場合の流れ場の物理的性質を流線図、等速度線図および等静圧線図を使って記述した。解析解では適用できる境界条件が限られる。数値解ではより柔軟に境界条件を適用できるけれども、自由表面の形状を適切に設定できるか否かが問題になる。そこで同一の問題を数値的に解いた。問題を解く際にラグランジュの補間公式に基づく補間と微分の手順を系統的に適用した。荒い格子と細かい格子を試した。数値解の精度を評価するために解析解と比較した。収束と計算時間についても検討した。パラメタを使って境界線を設定し、形状を調整することによって、境界線に沿う流速の計算で誤差0.15％以下を達成しほぼ自由表面に近い形が得られた。</datacite:description>
          <datacite:description descriptionType="Other">In this paper a complex potential solution for impinging jets was examined from a hydrodynamic perspective. The physical characteristics of the flow field were illustrated using a stream line diagram, velocity contour diagram and static pressure contour diagram. The same problem was then solved numerically. A series of interpolation and differentiation procedures based on the Lagrange interpolation formula were applied systematically to solve the problem. Two grid systems were tested, a coarse and a fine system. The numerical results were compared with the analytical results to evaluate accuracy. Convergence of solution and computing time were also evaluated. The free stream line was successfully described using parameters.</datacite:description>
