Abstract

Direct steam generation collectors are considered with the aim to improve the performance and reduce operating costs of solar electric generation systems. In this study a hydrodynamic model is developed to investigate the flow conditions of once-through direct steam generation (DSG) solar collectors. The hydrodynamic model comprises two main parts: flow pattern and pressure drop prediction. Flow pattern maps in typical DSG collector horizontal and inclined absorber tubes are generated. Two-phase flow frictional pressure drop correlations for the range of operating conditions DSG collectors are selected by comparison with experimental data for steam-water flow at conditions similar to the direct steam generation collectors. Pressure drop is evaluated for different operating conditions for both horizontal and inclined solar absorber tubes.
