The possible implementation of direct steam generation (DSG) in parabolic troughs in the Northweast region of Mexico is very limited, since there are no analyses of this type to try to define a first proposal for a solar plant. Recently, a methodology has been implemented to eliminate the convective coefficient h in order to model the DSG process in a simpler way. This methodology has been validated with experimental data from the DISS results from PSA. This methodology allows to evaluate the temperature evolution along the loop, the pressure drop and the flow pattern in a short time and with low computational resources. This allows generating the first evaluation of a solar field with parabolic troughs. Additionally, by applying a new practical efficiency limit for the conversion of solar radiation into work, the exergetic efficiency of the installation is evaluated. The results show that this first evaluation, seems to be adecuate acording to the results suggested in the open literature.

The implementation of direct steam generation in linear concentrators is limited mainly by the complexity and the high demand for computational resources of the models developed to predict the installation behavior. With this in mind, we introduce an innovative methodology to characterize the thermo-hydraulic behavior of direct steam generation in parabolic trough solar collectors, with a strong focus on two-phase flow phenomena. Our proposed approach has resulted in a generalized function that eliminates the need for the convective coefficient h and enables accurate prediction of the flow pattern within the receiver. By comparing our model with experimental data from the literature, we achieved remarkable Relative Squared Errors (RSEs) of less than 3% for temperature and pressure calculations, thus validating the robustness of our methodology. Moreover, we further showcased the practical application of our developed model by applying it to a specific case study conducted in Agua Prieta, Sonora (Northwest Mexico), where we considered the prevailing meteorological conditions.
