RAR RUS 7-13 Kenden Kara-kys Kuca08@mail.ru Solar energy resources in the Tyva republic The main problem of isolated areas of Tyva today is the lack of an effective electric power distribution system. The traditional way of solving theis problem is replacing older diesel power stations with the adjustment of their installed capacityies. AThe more attractive option serving to improve the electric power supply system of Tyva is the constructionng it with a focus on the local renewable energy resources. The solar energy, due to its reserves, availability, environmental safety, and usage scale, is the most important in the variety of renewable energy in decentralized parts of Tyva. To investigate the functioning conditions of using solar energy as part of an integrated electric power supply system it is necessary to study the modes of solar energy delivery. The indirect calculating methods for calculating solar radiation density on various surfaces are investigated in the article. The Byrd method was selected that gives the closest values to the observed actinometric station values. The monthly averages of the total amount of solar energy on a horizontal surface in the Tyva’s decentralized areas were calculated using the proposed method.

The shaping was performed using a numerical experiment. Various versions of the inlet channel geometry were designed based on the original one. Turbulent flow was then modelled for these versions by the Ansys Fluent software. A k-ω SST turbulent model was used. Aerodynamic resistance was subsequently calculated using the obtained numerical solution.

It has been shown that in the regime with moderate flow swirl at the diffuser inlet power struts have virtually no effect on the three-dimensional flow structure behind the stage. The Rreliability of this assessment is confirmed by a comparison between the computational and the experimental data. Therefore, if the input stream has a moderate swirl, it is possible to perform a 3D simulation of the flow in a diffuser with struts, by using the domain isolated from the last turbine stage and by setting the boundary conditions at the entrance to the diffuser according to the flow calculation in the last stage of the turbine without the diffuser. 10.5862/JEST.231.4 621.165–253.5:620.193.1 Gas turbine exhaust diffuser struts backward influence numerical simulation https://engtech.spbstu.ru/article/2015.94.4/ 4_kirillov.pdf

Such research is necessary since NPPs are required to participate in the electric load schedule and to regulate the frequency of electrical current, while the reactors have a low flexibility for participating in these modes. The study was performed for one of the previously developed draft versions of the NPP-2006 project with a VVER -type 1200 MW reactor, a K-1200-6,9 / 50 turbine and a TEAS. The issues, discussed in the article, concern static and dynamic turbine characteristics over the whole possible power range of the NPP unit in TEAS discharge mode with constant values of operating parameters of reactor and regulation of the turbine power by changing the value of the regenerative bleed-off. The study has been conducted with the goal of verifying that the NPP with a TEAS and the above-described power regulation parameters is in compliance with the regulatory on turbine power change rate for NPPs participating in the primary frequency control of the electrical current network.

Fatigue life is estimated by the linear damage accumulation rule and the strain life criterion with regard to the elastic-plastic material response. The initial material inhomogeneity is simulated by varying the cyclic hardening of the experimentally observed material fractions, ferrite and perlite. The results obtained on crack front evolution indicate that its predominantly occurs in the subsurface layers in the material element clusters with the smallest cyclic hardening. The simulated life scatter for several FE-mesh densities satisfactorily fits the experimentally obtained data at different values of stress amplitude and is more pronounced in the high-cycle regimes. It is shown that crack growth stage can reach 25% of the total fatigue life for smooth specimens.

The proposed self-regulating automatic stepless transmission allows to significantly improve s the technical characteristics of modern CVTs in relation to power and kinematic ranges, and also in design simplicity. In this investigation, the theoretical research results on the dynamics and the kinematics of the operating processes in impulse transmission on the example of an ATV are presented in the MATLab – Simulink visual programming environment.

The results showed that the proposed scheme of mechanical stepless transmission of impulse type has the property of self- regulating the velocity ratio. The transmission provides smooth acceleration and uniform motion of the vehicle. Applying the interaxle differential is not required. At slipping each of the wheels will transmit a tractive effort up to the limit of adhesion. At the same time the wheel lock to improve traction properties is not required.
