Modeling of coupled saturated steam-water spaces using quasi-steady state, quasi-numerical approach

Simulators are extensively used as a tool for industrial training, design and development. Nuclear and Fossil Power Plants employ a number of equipments & systems operating in the saturation pressure/temperature region. Methodology adopted in simulation & analysis of saturated steam & water spaces use multiple equations, complex algorithms and Steam Tables. When the computational models of saturated steam water space equipments & systems are interconnected or coupled with other models, the models become much more complex. These complex algorithms and steam tables adversily affect the speed of computation of these models. This paper proposes a quasi-steady state, quasinumerical modeling approach for steam water space system. This approach is efficient in coupling & combining saturated steam water space models with other models.
