Hydrodynamic Analysis of Direct Steam Generation Solar Collectors

Journal of Solar Energy Engineering, 1999
Direct steam generation collectors are considered with the aim to improve the performance of a parabolic trough collector leading to a reduction of operating costs of solar electric generation systems. In this study a hydrodynamic steady state model is developed and linked with a thermal model to optimize the performance of once-through direct steam ...

Advancements in the Field of Direct Steam Generation in Linear Solar Concentrators—A Review

Heat Transfer Engineering, 2013
Direct steam generation in parabolic trough or linear Fresnel collectors represents one interesting technological option for concentrating solar electricity production. Today's state of the art characterized by the first commercial plants in operation is a result of more than 20 years of intensive research on this topic.

Direct steam generation in parabolic troughs: Final results and conclusions of the DISS project

Energy, 2004
Abstract This paper presents a summary of the main results and conclusions achieved in the DISS (Direct Solar Steam) project. The test facility implemented at the Plataforma Solar de Almeria (PSA) in 1997–8, the so-called PSA DISS test facility, was operated for more than 3000 h in 1999–2000 and 2001 to investigate the Direct Steam Generation (DSG ...

Thermal modeling of a concentrator pipe composed with direct steam generation

Applied Solar Energy, 2012
Deflections along the pipes of solar concentrators used for direct steam generation in thermosolar plants lead to some structural problems, due to temperature gradients in radial and angular directions. In this work, a thermal analysis of an absorber copper-steel pipe is made, based on the solution of heat transfer equations in stable and transient ...

Transient characteristics of a parabolic trough direct-steam-generation process

Renewable Energy, 2019
Abstract Solar-powered direct steam generation (DSG) is attractive for power generation and industrial utilization due to the combination of renewable-energy source and clean energy carrier. An improved SIMPLE algorithm ensuring the dual roles of pressure acting on velocity and density fields is developed to realize thermo-hydraulic completely ...

Analytical modeling of direct steam generation solar power plants

Solar Energy, 2013
Abstract Analytical models for the physical processes governing direct steam generation line-focus solar thermal power plants are derived. Predictions compare favorably with the limited database available from published studies against which the accuracy of detailed model computations can meaningfully be assessed.
