A new method based on CFD (computational fluid mechanics) is used to estimate the energy consumption of DTS (double-tube socket) pneumatic conveying. The whole pipeline is divided into developing and fully developed parts. After CFD simulation of both parts the overall energy consumption is calculated. The results show that under the pressure gradient of 750 Pa/m in the developed part the predicted material flow rate is 10 t/h and the measurement material flow rate 8 t/h. Meanwhile the predicted gas consumption is 290 m3/h and the measurement gas consumption 240 m3/h. The predicted results are in fair agreement with the experimental results, suggesting that the new method is reliable and applicable.
