High-temperature Fluidized Receiver for Concentrated Solar Radiation by a Beam-down Reflector System

Optimization of Central Receiver Concentrated Solar

In this thesis, two new models are introduced for the purposes of (i) locating sites in hillside terrain suitable for central receiver solar thermal plants and (ii) optimization of heliostat field layouts for any terrain. Additionally, optimization of heliostat canting, is presented as an application of the heliostat layout optimization model. Using the site selection model, suitable sites are ...

A Numerical Study on Agglomeration in High Temperature Fluidized beds

Soft-sphere discrete element method (DEM) and Navier-Stokes equations were coupled with equations of energy for gas and solids to investigate the process of agglomeration in fluidized bed of polyethylene particles at high temperature. The Newton’s second law of motion was adapted for translational and rotational motion of particles and agglomerates. The cohesive force for polyethylene particles...

Carbon dioxide as working fluid for medium and high-temperature concentrated solar thermal systems

This paper explores the benefits and drawbacks of using carbon dioxide in solar thermal systems at medium and high operating temperatures. For medium temperatures, application of CO2 in non-imaging-optics based compound parabolic concentrators (CPC) combined with evacuated-tube collectors is studied. These collectors have been shown to obtain efficiencies higher than 40% operating at around 200...

Life Cycle Assessment of a High Temperature Molten Salt Concentrated Solar Power Plant

The well-known world energetic matter, mainly due to the worldwide growing energy consumption gone with a reduction of oil and gas availability, and to the environmental effects of the indiscriminate use of fossil fuels in our economy, is leading to the development of clean innovative technologies for the reduction of GHG emissions and the creation of a more sustainable economic structure world...
