Design of a Stabilize Device for Heavy Oil Transportation in Water Ring
During the long distance transportation of heavy oil by water ring,instability will occur under the action of gravity.In order to meet the demand of stable transportation of water-ring heavy oil,an innovative design method integrating TRIZ and Extenics is proposed.By analyzing the contradictions in innovative design and implementing effective extension transformation,a waterring heavy oil transportation stabilize device is designed.According to the principle of divergence analysis of a characteristic multi-value,two schemes are designed,in which the bottom liquid outlet is located at the entrance or exit of the stabilizing device.The N-S equation and the turbulence model have been used to describe the fluid flow.Taking the V0F model and the CSF model to track the oil-water interface,the numerical equation and analytical model have been established.The simulation results show that when the bottom liquid outlet is set at the entrance section of the stabilize device,the pipeline can better form the shape of heavy oil wrapped by water ring.
