Investigating Supercritical Bended Flow Using Physical Model and CFD

چکیده
The flow in the bend channel used as spillway chute is complex due to turbulence, presence of shock waves, and vibrations. These transverse waves can damage hydraulic structure. Our aim this paper investigate distribution water surface five curved channels with relative curvatures ρ , different bottom slopes (1%, 2%, 10%, 18%) three cross-sections. objective give a solution reduce height difference between inner outer walls. To achieve goal, we physical models patterns, explore critical zones, test several solutions have better performance. reliability accuracy numerical results were validated using modelling for each case tested. Moreover, comparison measured data, theoretical calculations, outcomes was done, find fitting law maximum wave number. Furthermore, an optimal position guide wall identified real project spillway. model simulation show good agreement; thus, play crucial role order study parameters, pressure, velocity field problems that occur these structures.

Investigating the Effects of Mass Transfer and Mixture Non-Ideality on Multiphase Flow Hydrodynamics Using CFD Methods
A numerical framework has been proposed to model the interacting effects of mixture non-ideality and mass transfer on hydrodynamics of a multiphase system using CFD methods.Mass transfer during condensation and vaporization is modeled by chemical potential at the liquid-vapor interface. Species mass transfers are related to the diffusion at the interface which in turn is related to the conc...

متن کاملThe Indication of Two-Phase Flow Pattern and Slug Characteristics in a Pipeline Using CFD Method
Multiphase flows are commonly encountered in oil and gas industries. The transport of multiphase flow causes the formation of slug, the increase of pressure drop and the possibility of phase changes therefore, a set of simulation runs was performed to predict flow regimes in a horizontal pipeline, and the results were compared with the Baker chart. The effects of small downward inclinations of ...
