Numerical Modeling of Wet Steam Flow in Steam Turbine Channel

In power station practice, work is extracted from expanding steam in three stages namely High Pressure(HP), Intermediate Pressure(IP) and Low Pressure(LP) turbines. During the expansion process in the LP turbine, the steam cools down and at some stages, it nucleates to become a two-phase mixture. It is well-acknowledged in the literature that the nucleating and wet stages in steam turbines are ...

Streams of Steam – The Steam Boiler Specification Case Study

FOCUS is a mathematics-based methodology for the development of distributed reactive systems. This paper sketches the expressiveness and the usefulness of the well-tuned concepts of FOCUS by its application of the requirements specification of a steam boiler, see [Abr96]. We demonstrate the support for non-specialists in formal methods by using userfriendly description techniques, here the stat...

Saturated steam process with direct steam generating parabolic troughs

The direct steam generation (DSG) in parabolic trough collectors is an attractive option regarding the economic improvement of parabolic trough technology for solar thermal electricity generation in the multi Megawatt range. The European DISS project has proven the feasibility of the direct steam generation under real solar conditions in more than 4000 operation hours. Within the European R&D p...
