Sunshape and reflector surface slope error distributions are significant elements in modelling the optical behaviour of a concentrating solar power system. Different tools implement these with various approaches. Discrepancies can easily accumulate simulations large system as result incorrect implementations. This study reviews verifies implementations two factors six that widely used for energy research: Tonatiuh, SolTrace, Tracer, Solstice, Heliosim SolarPILOT. The review incorporates...
In a concentrated solar power (CSP) tower plant, it is essential to understand the performance of subsystem formed by heliostat field and receiver, operated with an optimal aiming strategy that guarantees safety lifetime receiver while maximising performance. State-of-the-art studies optimise field, independently. However, are interdependent co-optimisation field-receiver necessary obtain configuration. Fast accurate annual assessments needed calculate energy output Levelised Cost Energy...
In open cavity receivers employed in solar paraboloidal dish applications, natural convection occurs and contributes a significant fraction of energy loss. Its characteristics hence need to be clarified so that it can effectively minimized order improve the system efficiency. The investigation loss from was undertaken numerically validated using published experimental results for four different receiver geometries. A good agreement between numerical obtained. Furthermore, all were...
The Australian National University has been undertaking a review of state-of-the-art in heliostat design, as part the Solar Thermal Research Initiative (ASTRI). Deep cost reduction is required to ensure solar tower technology becomes competitive, and achieve aggressive LCOE targets ASTRI other programs like U.S. Sunshot. This paper case study for new aims provide directions identify opportunities reduction. examines trends at both system level an individual collector level, make sense where...
This study examines experimentally the heat loss from a model solar cavity receiver. For this purpose, laboratory-scale cylindrical models with geometric aspect ratios (cavity length to diameter) of 1 and 2, aperture opening ratios(aperture diameter 0.5 1, were built. Each cavitywas subjected constant boundary inputvia heating cables, was operated at various downward inclinations. A carefully-applied coating Pyromark-2500 resistant paint on surface, in conjunction steady-state experimental...
Reforming of methane is practiced on a vast scale globally for the production syngas as precursor many commodities, including hydrogen, ammonia and synthetic liquid fuels. Solar reforming can reduce greenhouse gas intensity by up to about 40% using solar thermal energy provide endothermic heat reaction, traditionally supplied combustion some feed. This has potential enable derived fuels drop in replacements conventional with significantly lower CO2 than liquids (GTL) processes. However,...
At present, iron and steelmaking industry worldwide is going through the transition of decarbonisation to meet its goal reaching net zero by 2050. In addition, Australian facing own challenge processing lower grade ores with increasing gangue content. Two major pathways are direct reduction – electric arc furnace pathway (DRI-EAF) smelter-BOF (DRI-electric smelter-BOF) pathway. present work, a mass energy balance model basic oxygen (BOF) (EAF) have been developed using thermodynamic...
This process modelling study explored the behaviour of hydrogen-based direct reduced iron (DRI) manufacturing in a shaft furnace. Various performance parameters such as metallisation ratio (MR), consumption hydrogen per tonne DRI, production by-products, reactor energy demand and total demands for have been analysed with respect to temperature, ore grade (gangue content), reactant conditions. The HSC Chemistry (H: enthalpy, S: entropy C: heat capacity) SIM (simulation) module was employed...
