the effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Vibroacoustical Energy Flow through Straight Pipes
At lower relative (i.e., non-dimensional) frequencies, four propagating waves exist in fluid-filled pipes. Each of these waves carries energy in the pipe wall, while three waves carry energy in the fluid as well. The otherwise fairly complex dispersion laws for waves in pipes simplify in the frequency region considered to simple rodand beam-type laws. It is shown that these laws can be determin...
متن کاملLarge Eddy Simulation of Particle-Laden Flow by Using Solid / Liquid Two-Phase Flow Model
Achievement of a good performance in a Direct Numerical Simulation (DNS) of a particulate flow has been restricted to a low particle Reynolds number below a few hundreds due to the limitation of computational load by using a fine grid (Harada and Gotoh, 2008). Hence, in this study, to perform numerical simulations in higher particle Reynolds numbers, a Large Eddy Simulation (LES) by Smagorinsky...
متن کاملGeothermal Two-phase Flow in Horizontal Pipes
This paper reanalysed the 255 sets of geothermal two-phase flow data of Freeston et al (1983). A new void fraction correlation is proposed in this paper. The new correlation is derived from the analysis of two-phase flow velocity distribution using the Seventh Power Law as: To predict the two-phase pressure drop, an equivalent pseudosingle-phase flow having the same boundary layer velocity dist...
متن کاملSimultaneous Ldv Measurements of Gas and Particle Velocities in Two-phase Flow
An experimental investigation was conducted to simultaneously measure the instantaneous velocities of large particles and air in two-phase flow using Laser Doppler Velocimeter. Measurements at two Photo-Multiplier voltage settings are used to separate the signals from the small seeding particles that trace the air flow and the suspended solid particle based on the difference of scattered light ...
