The thermo-hydraulic study for the work fluid is an important topic in solar concentrator systems. In this investigation a model to simulate the variation of thermodynamic state for the mix water-steam and simple phases were carried out. The correlations more suitable for the operating conditions for heat transfer (boiling and condensation) and pressure drop in a two-phase flow were considered. Optical losses effects, previously studied, were included inside the current model (mirror reflectance variation with incidence angle and non-illuminated absorber length). The simulation results agreed with experimental data. The outside wall temperature of tubes for total absorber length were measurement, and inputs/outputs temperature and pressure for the bulk fluid were registered.
