The Gas Flow Simulation of Tokamak’s Inflatable Pipeline

Abstract:

Inflatable pipe is an important part of the tokamak's experimental device. This paper first introduces the composition, functions and working mode of the inflatable pipe. Then it's based on the fluid dynamics to establish model of the inflatable pipeline and the nodes. Finally, using the finite volume method to complete a numerical analysis of gas flow in the tokamak's pipeline. The results show that, if it needs to get the gas flow of the H2 that is 400 Pa•m3/s at the valve in the Pipeline, it needs to set the value of the inlet pressure that is 1.5 bar. The larger diameter of the pipeline, the more increase rate of gas flow in the pipeline.
