CFD analysis of pneumatic conveying in a double-tube-socket (DTS®) pipe

A pipeline with a bypass is widely used for the pneumatic conveying of material. The double-tube-socket (DTS®) technology, which uses a special inner bypass, represents the current state of the art. Here, a new methodology is proposed based on the use of computational fluid dynamics (CFD) to predict the energy consumption of DTS conveying. The predicted results are in good agreement with those from pilot-scale experiments.
