Abstract

Abstract: CO grid is generated by using an algebraic method. In this grid transonic full potential equation is solved by finite volumn method. The calculated results agree well with experimental data, while the computation time is reduced by a factor of 1/3~1/4 of one required in CH grid. Transonic analysis and design using this improved grid can be made not only for large aspect ratio wings, but also for small aspect ratio wings without any difficulties.

Key words: numerical analysis, transonic flow, design.
