A Study of effect of floating vegetation on the formation of exchange flow

A Study of effect of floating vegetation on the formationof exchange flowAmir Heshmatifar1, Mirmosadegh Jamali 2Department of Civil Engineering, Sharif University of Technology, Tehran, IranAbstractThis study is concerned with the effect of floating vegetation on the exchange flow resulting from negative heat flux on open water by surface cooling. The problem configuration is comprised of two regions: open water and aquatic canopy area with floating vegetation. The negative heat flux resulting from night cooling, for example, makes a density difference between open water and canopy area, and hence drives an intrusion of warm water into the open region at the surface. Velocity distribution is measured by PIV method. The experiments are done for a range of vegetation density (0 to 15%) and r ...
