Direct Steam Generation with Dish Concentrators

This paper presents current research on Direct Steam Generation (DSG) by the Solar Thermal Group at ANU. It includes ongoing work on a transient model for a dish steam cavity receiver that is suitable for model-based control of DSG as well as reporting on the experimental set-up on a new 500m paraboloidal dish solar concentrator. A comparison of two transient models of a dish steam cavity recei...

Buffer storage for direct steam generation

Fast reaction times and high discharge rates make steam accumulators a promising option for compensation of fast transients in insolation for solarthermal systems using steam as working medium. Using the volume of components like separator drums or heat exchangers for storage of pressurized hot water is a cost-effective approach to integrate buffer storage capacity. While the basic steam accumu...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

The Dynamic Behavior of Once-Through Direct Steam Generation Parabolic Trough Solar Collector Row Under Moving Shadow Conditions

Compared with recirculation and injection modes, once-through direct steam generation (DSG) parabolic troughs are simpler to construct and require the lowest investment. However, the heat transfer fluid (HTF) in once-through DSG parabolic trough systems has the most complicated dynamic behavior, particularly during periods of moving shadows caused by small clouds and jet contrails. In this pape...
