Abstract等角写像法はポテンシャル流れを解くための古典的な解法であり,今井はその著書「等角写像とその応用」1)でこの解法が色々な問題を解くのに有用であることを示している.筆者はこの本技術資料で,今井の文献に挙げられた多くのポテンシャル流れの問題を,数値的解法であるパネル法を用いて解き,解析解との結果を比較して,そのすべてにおいて非常に良い一致が得られることを示した.パネル法による解のすべてと等角写像による解の多くを解くためのツールとして,マイクロソフト社が無償で提供するVisual Basic 2010 Express を用いた.本解析を通じてVisual Basic 2010 Express が非常に使いやすく,流れのグラフィックス表示などわかりやすい形で解を表現できることが示された.

The conformal mapping is a classical method to solve potential flow problems. In 1979, Dr. I. Imai published a book in which he showed that the conformal mapping can be utilized to solve many problems of potential flow. The author of this paper applied the panel method to solved the same problems which Dr. Imai introduced in his book, and compared the solutions obtained by the two methods separately. The results of the comparison revealed that the two solutions obtained by two different methods agreed in very good accuracy in all problems. In this comparison, Visual Basic 2010 Express, which is supplied free from the Microsoft Corporation, was used as a development tool. All through the computations, Visual Basic 2010 Express proved to be very sophisticated in helping the easy coding of the programs, in operating the programs and in producing the results in not only numerical values but also in beautiful graphics expressions.
