Numerical Simulation on Flow Field inside the Drainage Valve of the Natural Gas Pipeline

Abstract:

In order to ensure safety and reliable operation of the natural gas pipeline drainage valve,the 3D numerical simulation on flow field characteristics inside the drainage valve of the natural gas pipeline under the different conditions of the seasons of winter and summer is carried out by using the standard model. In the tow different season condition, the streamline and velocity vector distribution inside the drainage valve has been studied. Under the two seasons conditions are studied. The results show that as the change of drainage valve opening the turbulence appear in the valve and the maximum value appears in the inlet,which the winter is larger than summer.The velocity vector distribution in the drainage valve is not the same and the larger velocity appears at the drain exit with the valve opening increasing. The differences in temperature, condensate discharge, condensate gas pipeline in different displacement,density and viscosity in the winter seasons and summer seasons results in the different characteristic.of the flow field characteristics inside discharging valve.
