froude number 中文意思是什麼
froude number
解釋
費魯德準數-
The water current flows over the top of the dentoid baffle to the hydraulic jump as additional momentum. while it is cooperated with a stilling basin, the flowing condition emerged in the basin may be improved greatly and the length and downstream water depth required by the basin can be decreased to a great extent. such an appliance may be also used to solve the problems of insufficiently dissipating water flow energy and aerating flow, which are often faced with those hydraulic engineering constraction as acted by high waterhead, great specific discharge and low froude number
本文通過齒墩頂部的擴散水舌所形成的附加射流，從上部射入水躍，即可改善消力池內的水流流態，又可降低第二共軛水深，減小水躍長度，增進水躍消能效果，同時還能解決大單寬、低佛勞德數條件下摻氣和消能不足的問題，試驗證實它是一種安全、經濟的消能工。 -
