Energy dissipation (head loss) by a hydraulic jump

작성자 Uploader : ezcivil 작성일 Upload Date: 2016-04-05변경일 Update Date: 2016-04-05조회수 View : 577

One of the most important engineering applications of the hydraulic jump is to dissipate energy in channels, dam spillways, and similar structures so that the excess kinetic energy does not damage these structures. The rate of energy dissipation or head loss across a hydraulic jump is a function of the hydraulic jump inflow Froude number and the height of the jump.

The mathematical formula for Energy loss in hydraulic jump is as follows:

ΔE = (y2-y1)^3 / (4y1y2)

y1 : water depth before hydraulic jump (m)
y2 : water depth after hydraulic jump (m)

*** 참고문헌[References] ***

ΔE = (y2-y1)^3 / (4*y1*y2)
