Noise Prevention Research in the Hyperbaric Oxygen Chamber by Flux Vector Splitting Format Academic Article uri icon


  • © 2013 IEEE. This paper describes the application of computational fluid dynamics(CFD) in noise prevention of hyperbaric oxygen chambers. The flux vector splitting format and matrix transformation are used in the calculation of flow field in the hyperbaric oxygen chamber. At first, this paper simplifies the model of the hyperbaric oxygen chamber, and calculates the conservative state equation by flux vector splitting format. Being auxiliary to initial conditions, boundary conditions, meshing, time steps, and other computing elements, this paper gets the transient distribution of the parameters of each time step from flowing start to its near stop. Through displaying the data by graphic, we get the flow velocity variation, the location of the shock wave, the variational trend of pressure, and the variational trend of temperature. This paper compares the numerical and experimental results. Their similarity degree is high and this proves the feasibility to design Low-noise hyperbaric oxygen chamber by this numerical calculation method.
