Hydrodynamics Analysis of Density Currents (Materials and Energy Research Center, 2008-10-01)Density Current is formed when a fluid with heavier density than the surrounding fluid flows down an inclined bed. These types of flows are common in nature and can be produced by; salinity, temperature inhomogeneities, ...
