Reynolds number; air; electricity; heat transfer; heat transfer coefficient; landscapes; simulation models; solar collectors; spectral analysis; transient flow; wind speed; wind tunnels
Abstract:
... Parabolic trough solar collectors are currently one of the most mature and prominent solar technology for the production of electricity. These systems are usually located in an open terrain where strong winds may be found, and could affect their stability and optical performance, as well as the heat exchange between the solar receiver and the ambient air. In this context, a wind flow analysis arou ...

Subject:
energy balance; equations; heat transfer; mathematical models; power plants; solar collectors
Abstract:
... Parabolic trough solar collector is the most proven industry-scale solar generation technology today available. The thermal performance of such devices is of major interest for optimising the solar field output and increase the efficiency of power plants. In this paper, a detailed numerical heat transfer model based on the finite volume method for these equipment is presented. In the model, the di ...

3. Numerical simulation of wind flow around a parabolic trough solar collector

Author:
Oliva, A.,   et al.   ; Hachicha, A.A.; Rodríguez, I.; Castro, J.;     Show all 4 Authors
Source:
Applied energy 2013 v.107 pp. 426-437
ISSN:
0306-2619
Subject:
Reynolds number; heat transfer; heat transfer coefficient; mathematical models; power plants; solar collectors; solar energy; wind speed; wind tunnels
Abstract:
... The use of parabolic trough solar technology in solar power plants has been increased in recent years. Such devices are located in open terrain and can be the subject of strong winds. As a result, the stability of these devices to track accurately the sun and the convection heat transfer from the receiver tube could be affected. In this paper, a detailed numerical aerodynamic and heat transfer mod ...
