A Numerical Study of the behaviour on Lock Volume Variations in Lock-Exchange Density Current in Cold Fresh Water

The behaviour of warm discharge through lock-exchange was investigated numerically, with the assumption that density taken as a quadratic function temperature. Simulations were conducted eleven different times varying barrier position. This work presented here is practical and can also enhance policy making towards protection aquatic ecosystems. Such behaviours are evident in lakes, especially holomictic lakes from thermoelectric power generating plants. sudden increase water temperature after may leads to ”thermal shock” killing life has become acclimatised living stable temperate environment. aim this investigation better fathom well, gain more insight into such flows. results show regimes flow dependent on size lock volume. general volume, difference Reynolds number. Effects back reflected waves propagation speed not significant for small volume simulations. A rapid collapsing fluid noticed simulations velocity decreases same phase. Propagation totally independent Cabbeling key at point where masses meet, well development Kelvin-Helmholtz instabilities. Relations describes various given Table (1 - 11). Though, there little variations scaling laws compared earlier studied cases by means salt water. Lastly, it will be interesting if measures eliminate effect other properly thepropagation frontal slumping
