Impact of the Confluence Angle on Flow Field and Flowmeter Accuracy in Open Channel Junctions

Open channel junction is one of the most common hydraulic structures that are used in various practical situations such as sewer, drainage, and flood control systems. Knowing the fluid flow behavior, is one of the most important topics in designing the efficient open channel junctions. The complexity and deviation of flow in the junction’s zone disrupts the proper functioning of the flowmeter d...

Test of Turbulence Models for Wind Flow over Terrain with Separation and Recirculation

Several two-equation turbulence models using isotropic eddy viscosity and wall functions are assessed by solution of the neutral atmospheric boundary layer over a flat surface and wind flow over twoand three-dimensional models and real terrain. Calculations are presented for wind flow over the Sirhowy Valley in Wales, an embankment along the Rhine in Germany and the Askervein Hill in Scotland. ...

Manipulating flow separation: sensitivity of stagnation points, separatrix angles and recirculation area to steady actuation.

A variational technique is used to derive analytical expressions for the sensitivity of several geometric indicators of flow separation to steady actuation. Considering the boundary layer flow above a wall-mounted bump, the six following representative quantities are considered: the locations of the separation point and reattachment point connected by the separatrix, the separation angles at th...

Varying flow in linear dichroism cells

The usefulness of linear dichroism (LD) in structure identification depends strongly on the orientation of the molecule in the linear dichroism cell. Hence, the fluid flow inside the linear dichroism cell which performs this act of orientation is of great importance. As such, this paper records the steps taken to identify the varying flow states in the cell, with changing rotation speed, and th...
