free surface boundary 中文意思是什麼
free surface boundary
解釋
自由表面邊界-
Finally a set of equations with initiate values for boundary value problem is established where the velocity potential and its normal derivative are unknowns. because the model includes the effects of both the time and space to the velocity potential of free surface, it can be applied to strong nonlinear wave. as examples, solitary wave is computed in the numerical flume
推導給出計算域內以所有節點波勢函數和波面位置高度的時間增量為未知量的線性方程組，並同時考慮時間因素和空間變位對波面勢函數的影響，在預設的計算精度下，通過時步內的循環迭代逐一確定每個時步上的波面運動位置，從而建立了一種可適于求解強非線性波浪變形計算的數值模式。 -
Free form surface reconstruction is a key step in reverse engineering cad modeling. on the basis of segmentation, an approach of b - spline surface reconstruction with complicated boundary constraints is addressed
基於復雜邊界約束和內部散亂逼近的b樣條曲面重構理論和技術的研究是本文的一個重點和創新之處。 -
The model is free from limitation through complex shape of rigid boundary and arbitrary deformation of the free surface, and thus has the adaptability to special practical situation
該方法不受流體變形程度和固邊界形狀的限制，因而具有特定的適應性。 -
In order to study the characteristics of the stepped spillway overflow comprehensively and seek for the measure to increase the energy dissipation of the stepped spillway at large unit discharge, the method of turbulence numerical simulation and model test are used to study the stepped spillway overflow. in view of the curved free water surface, complicated boundary condition and turbulence flow, it very difficult to simulate the stepped spillway overflow
為了對階梯溢流壩面流場特性進行全面的研究，同時探求在大單寬流量下提高階梯溢流壩消能率的措施，本文採用紊流數值模擬與實驗相結合，數值計算為主、實驗為輔的研究方法對階梯溢流壩面流場進行了較系統深入的研究。
