Gravity currents produced by lock exchange
WebFeb 25, 2002 · The constant initial speed of propagation (V) of heavy gravity currents, of density ρC, released from behind a lock and along the bottom boundary of a tank containing a linearly stratified fluid has been measured experimentally and calculated numerically. The density difference, bottom to top, of the stratification is (ρb−ρ0) and its intrinsic frequency … WebFeb 24, 2011 · Lock-exchange gravity current flows produced by the instantaneous release of a heavy fluid are investigated by means of high-resolution two-dimensional (2D) large-eddy simulation (LES) using a… Expand 58 Velocity structure, turbulence and fluid stresses in experimental gravity currents B.
