Энергоэффективность зданий и сооружений: практические шаги

Energy effectiveness of buildings and structures: practical issues

On September, 11–13th, In Saint-Petersburg the 17th international exhibition “BalticBuild” took place. In its framework the business program attracted the great attention of visitors. Including the conference “Energy efficiency in design, construction and building operation. Modern facade systems, technologies and materials in civil engineering” that was held on 12th of September.

Air exchange management in shipyard shops

At the present time a new design document “Ventilation and heating of shipyard shops” commissioned by the Department of shipbuilding industry, Ministry of Industry and Trade of Russian Federation, is being worked out. The second edition of the document was endorsed by the leading shipbuilders, design and research organizations. Government confirmation of the document is planned on December 2013.

Results of microclimate modeling in living quarters with different types of heaters

The features of microclimate creation in living quarters where outside air inflow comes through ventilation valves are studied with respect to different types of heat appliances (convection heaters and radiators). The numerical simulation was used. Hydrodynamic equations solving taken with initial and boundary conditions allowed us to obtain information about temperature distribution and air speed in the studied volume.

Model experiments on the coagulation-membrane post-treatment of complex wastewater

The possibility of "membrane activation" of the coagulation process was tested with the polystyrene latex model system. In addition, there was shown a lower rate of the electrolytic coagulation with the model system based on phosphate buffer, sodium chloride, an organic dye, gasoline, sodium sulfide than with a similar system adjusted to positive values of redox-potential using hydrogen peroxide.

Refinement of turbulent flow velocity characteristics

The basic laws of Prandtl semi-empirical turbulence theory were analyzed in the article. It was shown, that the Prandtl – Nikuradse logarithmic distribution of velocities are not strictly universal. The change of the first and second turbulence constants was analyzed on the basis of experimental data of I. Nikuradse. The logarithmic velocity profiles for smooth and rough pipes have been transformed.

Engineering kinematic theory of the contact earth pressure and its application to the static calculation of thin quay walls

A version of the engineering kinematic theory of contact earth pressure in the application to the water-transport and offshore structures was suggested in the article. A dimensionless static “compression – tension” diagram of the soil, presented by curvilinear function, was used in the method. In this case, the displacement of the limit point of the diagram is determined with the account of the plastic deformation modulus in the earth contact point.

Self-organizing numerical models of transient processes in water supply hydraulic structures of energy industries

Results of development of self-adapting complexes of numerical models, permitting calculation of complex water passageway systems with varying flow regime on separate parts (discharge; movement on the dry bottom, provided hydraulic head in free-flow downstream tunnel etc.). Given results of numerical simulation of real systems make it possible to consider proposed approach as efficient.

Development of methodological support of the automated hydropower potential calculation using geographic information systems

This paper is dedicated to the development and approbation of methodology and GIS-based tools for calculating hydropower potential of rivers, located in Russian Federation. The list of initial data and information sources used in research were described. The approaches and GIS-tools described in present paper allow executing an assessment of hydropower potential of the rivers in a short time on large areas.
