free overflow 中文意思是什麼
free overflow
解釋
自由溢流-
According to the hydraulic property of overflow weirs under steady flow, the flow patterns of overflow weirs were classified into free overfall and submerged overfall, and numerical models for unsteady flow were established to simulate the two flow patterns respectively
摘要為了對保水堰的交替水流進行數值模擬，依據保水堰恆定流情況下的工作特性，將保水堰的水流形態分成堰流和滿流兩種狀態，分別建立保水堰不同流態下的非恆定流數學模型。 -
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。
