Experimental Investigation of Turbidity Flow in 90 Degree Bend with Mobile Bed
Turbidity currents in the ocean and lakes are driven by suspended sediment. The vertical profiles of velocity and excess density are shaped by interaction between the current and bed as well as between the current and the ambient water. This paper presents 48 series of experiments in which saline gravity currents flow through a laboratory sinuous flume. flume contains three successive bends wit...

متن کاملFlow Variables Prediction Using Experimental, Computational Fluid Dynamic and Artificial Neural Network Models in a Sharp Bend
Bend existence induces changes in the flow pattern, velocity profiles and water surface. In the present study, based on experimental data, first three-dimensional computational fluid dynamic (CFD) model is simulated by using Fluent two-phase (water + air) as the free surface and the volume of fluid method, to predict the two significant variables (velocity and channel bed pressure) in 90º sharp...
متن کاملNumerical computation of turbulent gas-particle flow in a 90 degree bend: comparison of two particle modelling approaches
A numerical study into the physical characteristics of dilute gasparticle flows over a square-sectioned 90◦ bend is reported. Two approaches, namely the Lagrangian particle tracking model and Eulerian two fluid model are employed to predict the gas-particle flows. Renormalization Group based kmodel is used as the turbulent closure for both the approaches; however, for the Eulerian model, additi...
متن کاملEffect of Bend Curvature Ratio on Flow Pattern at a Mixing Tee after a 90 Degree Bend
Many nuclear power plants report high cycle thermal fatigue in their cooling system, caused by temperature fluctuation in a non-isothermal mixing area. One of these areas is the T-junction, in which fluids of various temperatures and velocities blend. The objective of this research is to classify turbulent jet mechanics in order to examine the flow-field structure under various operating condit...
