Research ArticleOpen accessAll words, across the recordNumerical Simulation of 2_D Turbidity Currents and Wall JetM.H. Shojaeefard, K. Goudarzi, H. Ghasvari JahromiDense underflows are continuous currents, which move down the slope due to the fact that, their density are heavier than ambient water. In turbidity currents the density differences arises from suspended solids. Vicinity of the wall make density currents and wall jets similar in some sense but Variation of density cause this flows more complex than wall jets. An improved … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 7,034 accessesView PDFCite
