A HYBRID 1-D AND DEPTH-AVERAGED 2-D NUMERICAL MODEL OF RIVER FLOWS

Numerical simulation of lava flows based on depth-averaged equations

Risks and damages associated with lava flows propagation (for instance the most recent Etna eruptions) require a quantitative description of this phenomenon and a reliable forecasting of lava flow paths. Due to the high complexity of these processes, numerical solution of the complete conservation equations for real lava flows is often practically impossible. To overcome the computational diffi...

BUPROPION-INDUCE D CLIMBING THROU GH D -1 AND D-2 DOPAMINE RECEPTOR ACTIVATION

Intraperitoneal (IP) injection of bupropion (3,6, amine (4,16 mg kg•') induced dose-dependent climbing in mice. The climbing response induced by both drugs were decreased in animals pretreated either with the 0-1 antagonist SCH 233<)0 or the 0-2 antagonist sulpiride. The α-adrenoceptor blocker phenoxybenzamine decreased the climbing induced by both bupropion and amphetamine, but the β-ad...

Numerical simulation of turbulent compressible flows in a C-D nozzle with different divergence angles

Compressible gas flow inside a convergent-divergent nozzle and its exhaust plume atdifferent nozzle pressure ratios (NPR) have been numerically studied with severalturbulence models. The numerical results reveal that, the SST k–ω model give the bestresults compared with other models in time and accuracy. The effect of changes in value ofdivergence half-angle (ε ) on the nozzle performance, thru...

A Depth-averaged 2-d Simulation for Coastal Barrier Breaching Processes

A depth-averaged 2-D model has been developed for simulating coastal barrier breaching processes. The model solves the generalized shallow water equations and the non-equilibrium sediment transport and bed change equations in a coupled fashion using an explicit finite volume method on a rectangular grid. It considers interactions among transient flow, strong sediment transport, and rapid bed ch...
