A study of head velocity variations for density currents with discharge and slope variations in a divergent cross sections [PDF]
علوم و مهندسی آبیاری, 2009 Studying the head velocity of density currents in reservoirs and seas is very important. One critical parameter largely affecting the head velocity of density currents is the variations of a river section in dams'' reservoirs. In the present study, using

Experimental Investigation and Dynamic Fractal and Multi-fractal Analysis of the Density Current Patterns [PDF]
مهندسی منابع آب, 2020 Density current is caused by a slight density difference with the environmental fluid. These currents are of two-phase current type. These currents are non-linear in nature, which are complex and sensitive to initial conditions.

Critical Richardson numbers and gravity waves [PDF]
Astronomy & Astrophysics, 2002 In this paper we present two new results. The first concerns the proper identification of the critical Richardson number Ri(cr) above which there is no longer turbulent mixing. Thus far, all studies have assumed that: Ri(cr) = Ri ( cr) = 1/4. (1) However, since Ri ( cr) determines the upper limit of a laminar regime (superscript ), it has little ...
