中文摘要 | 若忽略運動方程式中之加速度項,以及考慮微小擾動波情況,可利用線性零慣性模式來描述渠道中水流之流況。本文即以線性零慣性模式為基礎,再應用拉普拉斯轉換、拉普拉斯逆轉換定理與複變函數積分之殘值定理等數學方法,求解渠道中微小擾動波之傳播。文中分別選用單獨餘弦波、二角形波、梯形波以及單一急升波等四種水位歷線作為上游端之邊界條件,以解析渠道中之流況。文中並與中央隱式差分法之數值解做比較。除外,並利用普里斯曼非線性之零慣性模式,以比較及探討本文中線性化模式之精度及適用性。 |
英文摘要 | The analytical solution of the zero-inertia model based on the assumptions of neglecting the acceleration terms in the momentum equation and considering the small disturbance wave at boundary was deduced. In this study, Laplace transformation, Laplace inverse theorem, and complex integration by the method of residues were applied for solving the model. Four types of inflow stage hydrographs were respectively imposed at upstream and in order to analyze the wave propagation in downstream channel. They are single sinusoidal wave, triangular wave, trapezoid wave, and rapidly monoclinal rising wave. Implicit central difference method of finite difference scheme was simulated for comparison. Besides, Pressimann implicit scheme for nonlinear zero-inertia wave model was applied to investigate the accuracy and availability for the analytical solution of the linearized model. |
