Treatment of physical and numerical diffusion in fluid dynamic simulations
A computer code is developed to predict the behavior of the hydrogen gas in the containment aftet a loss-ofcoolant accident. The conservation equations for the four components, i.e., air, hydrogen, steam and water, are set up and solved numerically by decoupling the continuity and momentum equations...

| Summary: | A computer code is developed to predict the behavior of the hydrogen gas in the containment aftet a loss-ofcoolant accident. The conservation equations for the four components, i.e., air, hydrogen, steam and water, are set up and solved numerically by decoupling the continuity and momentum equations from the energy, mass diffusion and turbulence equations. The homogeneous mixture form is used for the momentum and energy equations and the steam and liquid droplets are assumed to be in the saturation state. |
