Vidnovluvana energetika| Summary: | The mathematical model for calculating the heat flux density com ing from the parabolic dish concentrator to the heat receiver was modified. The model takes into account the tracking error that occurs due to mechanical damage or software inaccuracies of the solar tracking system. The influence of tracking error on heat flux density and focal spot size at the heat receiver surface was investigated. The critical value of the defocus angle at which the heat flux density becomes minimal is determined.
The values of heat fluxes for mathematically ideal and real concentrators with surface aberrations and tracking error were modeled and compared. The average heat flux density for different combinations of tracking error and surface aberrations in the system was calculated and compared. |
