Flow field calculation of detector inside gas pipeline under discharge situation

摘要

The flow field calculation of the detector in gas pipeline under discharge situation was presented for the problem of speed control of the detector inside gas pipeline. The discharge model for the detector was established and based on the operating principle of the detector in gas pipeline. Based on the computational fluid dynamics theory, the computational fluid dynamics software was applied to generate the flow field model and simulate the numerical value. The flow field of the detector inside gas pipeline under discharge situation was simulated. The numerical analysis of the velocity field and pressure field were realized. Some features of fluid flowing through the detector model were analyzed based on the calculating results , and the different apertures of the discharge area were simulated. The results indicate a gas pipeline detector under discharge area is of a definite attempt. It can provide the assistant support for further study on the speed control of the gas pipeline detector.
