Numerical simulation of the flow field in the teetered bed separator
Abstract：The flow field in the teetered bed separator was simulated using a Spalart-Allmaras model for improving the separation efficiency and optimizing the structure. The flow velocity distribution and pressure distribution were studies using a computational fluid dynamics meth- od. The results show that the axial velocity distribution at the different teeter water rates is basically symmetrical along the radial direction. The radial velocity distribution is asymmetric and increasing gradually along the radial direction while decreasing near the wall. The solid particles near the wall could be separated effectively because of decreasing or even eliminating of the wall effect by designing the distributor with multiple holes. The underflow outlets should be in the low pressure zone. The separation of the particles occurs in the high turbu- lence region, and layer in uniform and stable fluid region.
