Distribution of wind pressures on the outer surface of the New Safe Confinement (NSC) is necessary to determine the unorganized air exchange from the NSC (outward or inward) with radioactive aerosols to the environment, since it is not hermetically sealed. The results show the discrepancy between the wind pressure distribution on the NSC outer surface in the small-scale 1:300 physical model of the...
Given the world trends in the use of biofuels of agricultural origin, Ukraine has considerable potential to develop this direction at the expense of a significant resource base. Solid biomass is mainly used for heat production in large or medium-sized district heating boilers and in domestic wood, pellet boilers, in furnaces and in fireplaces. The work is devoted to the research of burning of wood...
One of the disadvantages of solar power plants is that they do not produce electricity at night, so they cannot support the load of consumers. One of the reliable methods of increasing the efficiency of the use of photovoltaic power station (PPS) for consumers is the installation of energy storage. This study aims to investigate the efficiency of using a battery energy storage system (BESS) that is...
On the basis of the experimental values of temperature and absolute humidity of the tunnel air and the temperature of the walls of the rim of the deep tunnels of the Kyiv metro, the features and mutual influence of the earthen massif, the supply air environment and the operating modes of the mechanical system of reversible tunnel ventilation during the year are considered. On the basis of the CFD...
Topical matter of power supply for today is effective increase in the reliability of power supply in medium voltage overhead power systems by sectioning of lines with switching devices, such as disconnectors, controlled disconnectors or sectioning points. In such schemes, the manual approach to emergency management is used. This kind of schemes can be used where the overhead power lines are. Protective...
