Numerical simulation of radial separation of isotopes in a dedicated device

In the high-speed rotating special equipment, the gas pressure is exponentially distributed in the radial direction. The existence of the pressure gradient separates the isotope mixture gas in the radial direction. The separation effect of the isotope is reflected in the distribution of the component concentration field. It is solved by the component transport equation. In order to objectively describe the convection-diffusion law of components under high-speed rotating conditions 9 the component transport equation with pressure diffusion term is used to solve the concentration field. The numerical calculation of the high-speed rotating concentration field is realized. By comparing the theoretical solution under the isothermal rigid body condition with the numerical solution of the article, the feasibility and accuracy of the adopted solution method are verified. As the research progresses, the method of solving the component transport equation with pressure diffusion term will be applied to solving the separation performance of special equipment. (authors)
