Description

Data used for the time resolution analysis during spring equinox, and for the set of days vs single design day comparison. The meaning of the different variables is detailed below. Note that "_e" refers to the Eastern receiver half, "_o" to the Western one. Thermal results: - L_tube: tube length [m] - N_panel: number of panels of the receiver - T: tube temperature, outer wall [K]. 3D matrix dimensioned as: (circumferential divisions in one tube half, from back to front)x(axial divisions following the flow path)x(time interval) - T_film: tube temperature, inner wall [K]. 3D matrix dimensioned as: (circumferential divisions in one tube half, from back to front)x(axial divisions following the flow path)x(time interval) - dt_ext: external tube diameter [m] - inc_t: angular position for the limits of the circumferential cells [rad] - thickness: tube thickness [m] - vector_time: time intervals Stresses resuls: - T_total: Tube temperature at the tube crown (most critical spot) [K]. 2D matrix dimensioned as: (axial divisions following the flow path)x(time interval) - eps: equivalent strain at the tube crown (most critical spot) [-]. 2D matrix dimensioned as: (axial divisions following the flow path)x(time interval) - gvm: equivalent stress at the tube crown (most critical spot) [MPa]. 2D matrix dimensioned as: (axial divisions following the flow path)x(time interval) - vector_time: time intervals
