Many attempts are made worldwide to create cheap, efficient, and eco-friendly water desalination systems. Passive solar stills (SS) considered be such. This paper presents the results of experimental theoretical investigation effects using phase-change materials (PCM) on performance SS. The experiments were conducted for two paraffin waxes, as PCM 1.0, 2.5, 5.0 kg used. studies used validate a mathematical model, which was based energy balance ordinary differential equations. equations...
Important parameters used for adsorption chillers, e.g. cooling capacity, coefficient of performance, are strictly dependent on heat and mass transfer conditions between adsorbent the cooling/heating medium. With aim energy efficiency increasing it is essential to reduce resistance. Different bed configurations exchangers constructions recommended application. In paper review commonly configurations, i.e. loose-grain beds or fixed beds, presented. Also, different technology were described....
An application of latent heat thermal energy storage systems with phase change materials seems to be unavoidable in the present world. The allow for storing excessive during low demand and then releasing it peak demand. However, a material is only one components system. second part exchanger that allows transfer between fluid material. Thus, main aim this review paper systematize knowledge about exchangers used systems. Furthermore, operating parameters influencing time exchangers,...
Searching for patterns in conceptual models is useful a number of purposes, example revealing syntactical errors, model comparison, and identification business process improvement potentials. In this contribution, we introduce formal approach the specification matching structural models. Unlike existing approaches, do not focus on certain application problem or specific modelling language. Instead, our generic making it applicable any pattern purpose most languages. order to build sets...
Empirical studies attest that conceptual models created in distributed modelling environments often vary heavily the way their respective model elements are labelled. Although same issues being modelled, different names chosen by involved persons. By this, analysis and comparison of models, which is required for subsequent integration, extremely challenging time consuming. Literature reveals several approaches addressing this problem either manually or semi-automatically integrating existing...
Research portals are a means to present, discuss, and advance scientific findings. They web-based knowledge management tools for research communities. foster collaboration among community of scientists, funders, political decision-makers. However, communities might not possess the experience required design portal. The authors support them by analyzing status quo existing providing respective improvement perspectives. ask what typical characteristics such how these can be used evaluate...
This paper presents the results of numerical tests on elements an adsorption chiller that comprises a sorption chamber with bed, condenser, and evaporator. The simulation is based data geometry prototype refrigeration appliance. this problem unique has not yet been performed, so far, no phenomena occurring in systems real scale carried out. presented are part research covering entire spectrum designing chiller. full process modeling thermal flow taking place abovementioned components...
The use of blade slots is one the passive methods controlling flow in a fan impeller. Numerical CFD analyses indicate possibility point separation inter-blade space depending on various configurations aperture arrangement. Bench studies confirm changing increase total pressure and internal efficiency. Additionally, changes affect noise level during operation.
Adsorption chillers are a promising alternative to traditional compressor-based devices. can be supplied with low- or medium-temperature waste heat from renewable energy sources. In addition, they used for water desalination purposes. Thus, the adsorption unique devices that meet essential problems of modern world: need limit negative impact humankind on natural environment and growing access drinking water. However, also have disadvantages, including ineffective operation large size....
Visualizing the contents of knowledge management systems allows for better comprehensibility base, gives a condensed overview, and provides entry points to particular items. In this context, two different visualization approaches have been proposed in literature. On one hand, algorithm-based introduced, which are capable automated generation reproducible visualizations. other visualizations such as maps be created individually by domain experts. paper, we propose combined approach dynamic...
