摘要： A control method for optimizing generated power of a solar-aided coal-fired power system under off-design working conditions sets maximizing generated power without changing main steam flow rate as a control goal. A solar-coal feedwater flow distribution ratio is adjusted to adjust water flow rate heated by a solar heat collection system, so as to achieve the control goal. Control steps include reading relevant information; calculating the water flow rate range heated by the solar heat collection system, and an applicable solar-coal feedwater flow distribution ratio range; establishing a correspondence between the generated power and the solar-coal feedwater flow distribution ratio within this range; selecting a solar-coal feedwater flow distribution ratio corresponding to the maximum generated power; and adjusting the water flow rate entering the solar heat collection system to an optimized value. The present invention can flexibly control the solar-coal coupling and improve the economy.

摘要： A loop heat pipe with a vapor-liquid two-phase flow injector, including: an evaporator, the vapor-liquid two-phase flow injector, a boiling pool and a condenser. The two-phase flow injector has a central vapor inlet and a circumferential liquid inlet, and is connected to an outlet of the evaporator and an inlet of the boiling pool. The condensate inlet of the condenser is connected to an outlet of the boiling pool. An outlet of the condenser is connected to the evaporator. With the vapor-liquid two-phase flow injector, the invention can directly introduce a part of the supercooled liquid working medium to the boiling pool without passing through the evaporator, solving the problem of insufficient liquid supply for the boiling pool and increasing the driving force for the system operation. Therefore, the invention enables the efficient cooling of electronic devices and the long-distance heat transfer.

摘要： A method for calculating the damage of a carbon fiber composite reinforced polymer (CFRP) composite under an action of a single lightning current component with a fast-rising rate is disclosed. Through the obtained dynamic impedance curves of the CFRP composite under the action of the non-destructive lightning current component, the anisotropic conductivity of the CFRP composite under the action of the single lightning current component with specified parameters is extrapolated based on pre-designed lightning damage simulation conditions. The anisotropic conductivity is taken as the initial condition of the conductivity of the CFRP composite in the coupled thermoelectric simulation model, which is able to better simulate the real lightning effect on the CFRP composite, and is able to more accurately obtain the lightning damage of the CFRP composite and analyze the relationship between the lightning damage parameters.
