Abstract This paper describes the development of ray tracing models for a 500 m dish concentrator. Two distinct types of model have been created: (1) a model in OptiCAD based on the generic dish design, which uses design values for mirror facet geometry, and averaged values for mirror facet slope and pointing error; (2) a model in Tonatiuh which incorporates measured values of these parameters, for the prototype dish completed in 2009. In both cases the goal is accurate prediction of the three-dimensional flux distribution in the focal region, in particular as an aid to receiver design.

This paper describes a dynamic model of a steam cavity receiver and presents results from simulations performed using this model in TRNSYS 16. The results are compared with experimental data to inform the calibration of specific model parameters. Using the experimental data obtained from the SG4 500 m2 dish at the ANU, it is possible to select a set of model parameters that produce good agreeme...
متن کاملAnalysis of the Radiation Flux Profile of the 100 Sun Promoteo Facetted Dish Concentrator
All PV systems have cells or groups of cells connected in series in order to build up voltage and minimise current. Because current is almost linearly dependent on the incident light, the current in a string of identical solar cells will be limited by the cell with the least illumination. It is therefore important to achieve a flux profile as uniform as possible. Typically for dish concentrator...
متن کاملAmmonia Receiver Design for Dish Concentrators
This paper describes a general method for evaluating receiver designs for ammonia-based energy storage with dish concentrators. The method involves ray-tracing to determine the concentrated solar flux profile on the reactor surface, followed by a simulation which calculates reaction extents and heat losses. In this paper, five receiver designs were investigated with varying cone angles and plac...

In this paper, a multi-layer and multi-dish model was proposed for a multi-dish concentrator system. Based on the model, the flux distribution of focal plane was calculated by Monte Carlo ray tracing method (MCRTM). The results show that the multi-dish concentrator system is composed of three different focal length parabolic surfaces. The design parameters calculated from the model have a good ...
