中文摘要 | 本文應用有限體積法及四階Runge-Kutta time stepping來求解三維非穩態Euler 方程式。矩形翼及 ONERA M6 機翼被選取來印證所建立之計算程式對三維流場的求解能力。 五個測試項目的計算結果與實驗數據及由其它方法所獲得的計算結果相比較,合理良好。證 實了此程式在次音速,跨音速,及超音速三維流場的適用性。 |
英文摘要 | The three-dimensional unsteady Euler equations are solved using the four-stage Runge-Kutta integration scheme. A finite-volume spatial discretization is applied to the equations written in body-fitted curvilinear coordinates. Applications of the computer code developed are presented for compressible flows over finite wings with different geometries and flow conditions. Solutions comparing with experimental data and results from existing codes are given. |
