Description
The paper investigates the applicability of a drift-flux approximation for calculations of strongly transient two-phase flows in advanced computer codes. For this purpose a blowdown problem of a one-sided closed duct was calculated using three different methods: an ordinary drift-flux approximation; a refined drift-flux approximation; a six-equation model. A sixth differential equation for the relative velocity is derived. This differential equation will be simplified leading to both drift-flux approximations. The result of all three methods are compared and discussed
