Re,




here is my theme entitled "flow of miscible gravity current"; that is to say a gravitational current is flow of a fluid within another ambient fluid of different density by a mixing phenomenon (Propagation of the gravity current), driven by a dam break, or by the exhaust accidental gas in the atmosphere or gallery. Gravity currents are also found in the environment such as in snow avalanches, the intrusion on the surface of the sea from river waters at the mouth. My research work to study in this thesis: a flow of a dense fluid (salt water) within a less dense (freshwater) miscible. The control parameters of this study are related to the difference of the density, the diffusion, the viscosity, the height as well as the fraction of the depth of the gravitational current.

(the problem I encountered in mass diffusion under the effect of density difference such as saline fluid density 1200Kg / m3 and soft fluid density 998.20 Kg / m3)






Thank you.
