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., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0061883000, レポート番号: JAXA-RM-12-013}, title = {ポテンシャル流れの計算法: パネル法と等角写像法との比較}, year = {2013} }
