NUMERICAL SIMULATION FOR FLOWS IN A SYMMETRICAL CONFLUENCE USING QUASI-3D NUMERICAL MODEL FOR FLOOD FLOWS

A case study of flood dynamic wave simulation in natural waterways using numerical solution of unsteady flows

Flood routing has many applications in engineering projects and helps designers in understanding the flood flow characteristics in river flows. Floods are taken unsteady flows that vary by time and location. Equations governing unsteady flows in waterways are continuity and momentum equations which in case of one-dimensional flow the Saint-Venant hypothesis is considered. Dynamic wave model as ...

3D numerical simulation of gaseous flows structure in semidetached binaries

The results of numerical simulation of mass transfer in semidetached non-magnetic binaries are presented. We investigate the morphology of gaseous flows on the base of three-dimensional hydrodynamic calculations in interacting binaries of different types (cataclysmic variables and low-mass X-ray binaries). We find that taking into account of a circumbinary envelope leads to significant changes ...

numerical simulation of downslope flows in a confined stratified region

geophysical fluids such as atmosphere and ocean often have stable density stratification; hence internal gravity waves are generated and propagated through them which are important in momentum and energy transfer in these media. these waves are also believed to generate layered structures in such media. recently there have been numerous theoretical, experimental and numerical studies on the way...
