Composite phase-change materials (PCMs) exhibit significant potential for enhancing the thermal performance of building walls. However, previous studies have generally lacked detailed investigations PCM-integrated walls under cold climate conditions. Therefore, in order to evaluate and wall adaptability hollow bricks with composite PCMs climates, a brick model was created by filling PCMs. Then comparative test conducted between PCM-filled conventional non-PCM-filled bricks. The experimental...

Solar air collectors are widely used for the heating of buildings in cold areas owing to their high light–heat conversion rate, non-freezing medium, and low manufacturing cost. However, intermittency solar energy conflicts with user's comprehensive demands, thereby hindering promotion collectors. To solve above issue, this study, a collector model new heat storage device (Type 2) was designed by comprehensively considering five factors, such as phase-change temperature, capacity, transfer...

The preservation of heritage buildings is beyond doubt an important problem today. examination a building involves number problems, viz. missing design documentation, the need to find extant reports about technical condition structures and reconstruction projects prepared by different organizations, nonconformance data contained in drawings documents organizations. In this paper abovementioned problems are reviewed exemplified case federal heritage-listed "Ekaterinburg State Academic Opera...

Abstract The problem of conservation energy sources is actual in many countries. strategies developed countries are aimed at renewable sources. For instance, European Union has already a long-term strategy ENERGYSTRATEGY 2050 to reduce greenhouse gas emission by more than 80-95% from 1990 levels. Russian Federation also the national program “Energy saving and improvement efficiency for period until 2030”. distinctive feature system development decentralized supply on large territories....

Introduction. Being an integral part of the modern construction, concrete is a complex nonlinear material. The behaviour depends to large extent on stress–strain state and loading history. Among structures newly constructed reconstructed buildings, there are number elements operating in conditions triaxial state, alternating cyclic loading. A phenomenological material model used numerical methods can serve as universal tool that allows describe behavior under such conditions. aim research...

Some results of investigation energy separation mechanism included in numerical model equations air spiral flow appearing Ranque-Hilsch vortex tube are presented the article. Standard k-ε turbulence had been used simulations. It was found that make possible to predict effect by using special semi empirical term conservation equation which accounts for heat conductivity effects.

Dukan dam is an important hydraulic structure in Iraq used for water storage, flood control, and electricity generation. During earthquakes, this can be subjected to varying degrees of damage depending on the intensity duration seismic event. In article, will analyzed during assumed earthquake using ABAQUS software. The behavior under load investigated. process, a two-dimensional finite element model central part dam, containing maximum height, was created, taking into account geometric...

Introduction. In recent decades, numerical methods for calculating concrete and reinforced structures have developed significantly, taking into account the physically nonlinear behavior of material. Such methods, in comparison with analytical ones, make it possible to describe work material more accurately reflect main features its stress–strain state. This makes perform cost-effective and, some cases, reliable design solutions. Concept limit surface plays an important role methods. Limit...
