Resumen:

A theoretical analysis was carried out using the homogeneous heat conduction equation in the cylindrical coordinate system using only two dimensions (r, ?). The finite-difference numerical method was used to propose a solution and obtain a temperature profile. Additionally, it is necessary to know how the thermodynamic properties of geothermal brine are affected by the solute mass fraction increase. The objective of this theoretical analysis was to complement the experimental tests carried out for direct steam generation (DSG) with annular two-phase flow patterns for low powers in parabolic trough concentrators with carbon steel receivers.
