Trough solar thermal power generation case

Which concentrating solar trough is the cheapest?

Among the concentrating solar collectors, the parabolic trough is the most developed, cheapest, and widely used for large-scale applications in harnessing solar energy. However, it is not yet cheaper than conventional fossil fuels, and improvements and developments in the PTC are a must . 2.2. Parabolic dish Sterling engine

How to increase thermal efficiency of parabolic trough solar collector with tube receiver?

The numerical analyses indicated that the thermal efficiency of the parabolic trough solar collector with tube receiver can be increased up to 8% by inserting a perforated plate in the tube receiver. Fig. 7. Schematic diagram of tube receiver with perforated plate insert developed by Mwesigye et al. , .

Are parabolic trough solar collectors reliable?

Parabolic trough solar collectors are also reliable and have a long lifespan. They are not as susceptible to weather damage as other types of solar collectors, such as photovoltaic panels.

Are symmetric and asymmetric corrugated tubes suitable for a parabolic trough solar collector?

Symmetric and asymmetric outward convex corrugated tubes were introduced by Wang et al. , as the metal tube of tube receiver for a parabolic trough solar collector system (SCPTR and ACPTR) to increase the overall heat transfer performance (as shown in Fig. 9).

Is a forced convection heat transfer turbulent fluid flow in a parabolic trough solar collector?

A forced convection heat transfer turbulent fluid flow inside the tube receiver of a parabolic trough solar collector was numerically researched by Seyed et al. , using CuO–water and Al 2 O 3 –water nanofluids as HTF.

Can nanofluids improve the thermal efficiency of a parabolic trough solar collector?

The numerical results indicated that using nanofluids as HTF can enhance the thermal efficiency of a parabolic trough solar collector with tube receiver effectively compared with using pure water as HTF.
