The application of complex network time series analysis in turbulent heated jets
(2014)In the present study, we applied the methodology of the complex network-based time series analysis to experimental temperature time series from a vertical turbulent heated jet. More specifically, we approach the hydrodynamic ... -
Horizontal round heated jets into calm uniform ambient
(2009)In this article, we investigate horizontal, round, turbulent buoyant jets that discharge in a homogeneous calm ambient fluid. In a series of experiments performed, the initial jet Richardson numbers ranged from very small ... -
Integrated environmental and hydraulic design of Xerias river, Corinthos, Greece, training works
(2004)The modern design of flood protection and training works in cases of major natural streams and creeks, requires a fine balance between a sound engineering approach in all engineering aspects on one hand, and an environmentally ... -
Nonlinear time series analysis and clustering for jet axis identification in vertical turbulent heated jets
(2014)In the present work we approach the hydrodynamic problem of discriminating the state of the turbulent fluid region as a function of the distance from the axis of a turbulent jet axis. More specifically, we analyzed temperature ... -
On the entrainment coefficient in negatively buoyant jets
(2008)Integral models proposed to simulate positively buoyant jets are used to model Jets with negative or reversing buoyancy issuing into a calm, homogeneous or density-stratified environment. On the basis of the self-similarity ... -
Spreading of buoyant jets and fountains in a calm, linearly density-stratified fluid
(2010)Round turbulent buoyant jets and fountains issuing vertically into linearly densitystratified calm ambient were investigated experimentally. The terminal (steady state) height of rise and the elevation of horizontal spreading ... -
Vertical buoyancy preserving and non-preserving fountains, in a homogeneous calm ambient
(2008)Experiments were conducted on the maximum and terminal penetration depths of fountains of light fluid, issuing vertically downwards into quiescent denser fluid. Fresh water jets into saltwater, and hot water jets into fresh ...
