Abstract

Obviously, one of the greatest challenges facing the world today is breaking fossil fuel dependence and promoting the development of new and renewable sources of energy that can supplement and, where appropriate, replace the diminishing resources of fossil fuels. Solar energy is clearly one of the most promising prospects to these problems since it is non-pollutant, renewable, and available everywhere in the world although with varying intensity. Ray tracing is an important tool for the design of the receiver elliptical–hyperboloid concentrators (EHC). However, the information about ray tracing, and flux distribution on the receiver of the EHC determines the size of the receiver using OptisTM Ray-trace software.

The present study concerns the effect of variation of the solar azimuth angle on the flux distribution on the receiver area of the EHC is examined by moving the solar energy source along the x-y plane of the aperture major axis from 0° to 90° with an increment of 15° intervals. For each azimuth angle variation, one maximum optical efficiency is observed in those variations. The maximum optical efficiency observed for each angle decreases, as the solar source is moved from 0°-90°. Results presented also show the distribution of the concentrated radiant energy over the receiver/absorber.
