A simple, mathematical model of the steady state performance of a condensing steam injector is developed based on one-dimensional conservation equations. The model involves two distinct flow regions-a stratified annular flow and a downstream dispersed flow. The former regime is modeled using a two fluid, non-equilibrium formulation while the latter is described by a homogeneous non-equilibrium model. The flow regime transition point is not calculated from first principles but must be described empirically. The model is applied to the simulation of experimental data. Good accuracy is achieved especially in cases where a significant condensation potential exists. The major modeling deficiencies are the lack of a predictive flow transition and the need for empirical closure relations for interphasial exchanges and shock calculations. More fundamental experiments are required before qualitative analytical model improvements are possible. |
