TL;DR: This study reviews and verifies the implementations of these two factors in six tools used for optical modelling in solar energy research: Tonatiuh, SolTrace, Tracer, Solstice, Heliosim and SolarPILOT.

TL;DR: In this article, an integrated model for an axisymmetric helical-coil tubular cavity receiver is presented, incorporating optical ray-tracing for incident solar flux, radiosity analysis for thermal emissions, computational fluid dynamics for external convection, and a one-dimensional hydrodynamic model for internal flowboiling of water.

TL;DR: A stochastic optimisation method adapted to illumination and radiative heat transfer problems involving Monte-Carlo ray-tracing is presented and efficient receivers are identified using a moderate computational cost.

TL;DR: In this article, a new tubular cavity receiver for direct steam generation, called SG4, has been built and tested on-sun based on integrated optical and thermal modelling, which achieved an average thermal efficiency of 97.1±2.1% across several hours of testing, and reduced the losses by more than half, compared to the modelled performance of the previous SG3 receiver and dish.

TL;DR: In this paper, the authors evaluated the annual dynamic performance and techno-economic feasibility of a solar fuels process driven by concentrated solar power (CSP), and developed a perfect one-day-ahead forecast scheduler to regulate the supply of solar syngas to the downstream Fischer-Tropsch (FT) synthesis, to minimise these ramp-up events.
