5 FAQs about [Dynamic solar collector detection]
Can a solar tower collector system be used for solar power generation?
In this work, a solar tower collector system for solar power generation was constructed and the experiment was carried out. An integrated dynamic simulation model consisted of heliostat field and air receiver sub-models was developed with experimental validation. The main outcomes of this study can be summarized as follows:
Can heliostat field and solar receiver be used as a dynamic model?
Thus, it is essential to develop a dynamic model based on a real heliostat field and solar receiver, which would be used to investigate the dynamic performance of a solar collector system after careful validation and be employed to check and optimize control strategies.
How is solar energy incident to the receiver aperture determined?
The solar energy incident to the receiver aperture is determined by the heliostat field model. Table 2. Different steady performance experimental cases. The thermal efficiency of the air receiver is related to the receiver outlet temperature and air mass flow rate.
What are the numerical models of solar receivers?
Apart from experiments, numerical models of solar receivers can be divided into the detailed model and the simplified model. The detailed model is based on CFD tools, such as ANSYS Fluent, for steady-state analysis and optimization.
What are the relative errors of a solar energy receiver test?
The relative errors of the maximum flux density and the total collected solar energy between experiment and simulation are 3.81% and 3.05%. During the receiver test, the receiver outlet temperature can reach above 880 °C. The pressure loss inside the air receiver is 0.88% when the inlet pressure is above 280 kPa.
