“…In the outfield service of the rolling bearings, the service loads or missions can be tracked for reliable life consumption assessment and individual life monitoring. Referring to the individual life monitoring concept of aircraft and engines [16][17][18], this section mainly discusses the individual life monitoring methods for rolling bearings based on load monitoring and mission monitoring. Moreover, the online life management method for rolling bearings is also provided.…”

“…However, these methods might be limited in some aerospace contexts in which the product's space and weight strictly restrict the placement of the monitoring sensors. Life consumption assessment is another solution with which to achieve individual life monitoring, which has been widely studied and applied in aircraft and engine usage [16][17][18]. It is realized based on the product's monitored service loads or missions and Miner's cumulative damage theory.…”

Rolling bearings are critical rotating components in aerospace and high-speed trains. The service loads of rolling bearings are generally different from each other, causing significant differences in their damage degrees and reliable life potential. To ensure bearing reliability during service, a reliable life consumption assessment and individual life monitoring method is proposed. Firstly, a small-sample reliable life evaluation method is established based on an accelerated life test conducted at a constant load or load block spectrum before delivery, by which the lower confidence limit of the reliable life of the rolling bearing under any service load can be calculated with the required confidence and reliability. Then, the confidence limits of the reliable life consumption percentage and remaining reliable life percentage for each rolling bearing can be evaluated in real time according to their online monitoring loads and Miner’s law. By this means, individual life monitoring and online life management can be conveniently realized. Compared with traditional bearing life management methods, which do not consider service load differences, this method can more effectively ensure service safety and simultaneously maximize the life potential of bearings.

Complex cycles with cyclic air intercooling are used to increase the energy efficiency of gas turbines. A modern and widespread way to improve the cooling process is to humidify the working fluid (cyclic air). The efficiency of wet compression primarily depends on the intensity of evaporation and heat exchange of droplets with the air flow, which begins to increase sharply when the effective diameter of droplet spraying decreases to 20 lm. It is proposed to use a contact heat exchanger to obtain a finely dispersed flow of water in the flow path of a gas turbine. The operation of such contact heat exchanger called aerothermopressor was investigated in this paper. CFD simulation of the water droplet evaporation process in the aerothermopressor airflow was carried out. Calculations were carried out for three variants of evaporation of water injected into the air flow: complete evaporation of water droplets in the evaporation chamber, additional evaporation of water droplets in the diffuser and incomplete evaporation, with obtaining smaller droplets at the outlet of the aerothermopressor diffuser. Efficiency of the aerothermopressor application in the gas turbine circuit for contact cooling of cyclic air is analyzed. It has been revealed that the aerothermopressor allows increasing the cyclic air pressure between the compressor stages by 2-10%, which will lead to a decrease in the compression work in the compressor stages and makes it possible to increase the gas turbine engine efficiency by 1-2%.

“…The enhancement of PVT is promising for solar energy utilization (Chen et al , 2019) in solar trigeneration systems which examined that a PVT-based collector obtained the highest solar coefficient of performance and solar utilization factor. Isaiah et al (2016) investigated the life consumed at 100 MW of power used in an IcGT along with wind energy. The analysis on optimization of exergy analysis of a solar-driven trigeneration cycle is dealt in Bellos and Tzivanidis (2017a, 2017b), where eight different working fluids are examined in the ORC where toluene with n-octane and Octamethyltrisiloxane resulting in maximum exegetic output (29.42%, 28.50% and 28.35%, respectively).…”

Purpose This paper aims to analyze energy and exergy analysis of solar-based intercooled and reheated gas turbine (GT) trigeneration cycle using parabolic trough solar collectors (PTC) with the use of MATLAB 2018. Design/methodology/approach In the first section of this paper, the solar-based GT is validated with the reference paper. According to the reference paper, the solar field is comprising 30 modules in series and 35 modules in parallel series, where a total of 1,050 modules of PTC are taken into consideration. In the second part of this paper, the hybridization of the solar, GT trigeneration cycle is analyzed and optimized. In the last section of this paper, the hybridization of solar, intercooled and reheated GT trigeneration systems is examined and compared. Findings The results examined the first section, the power produced by the cycle will be 37.34 MW at 0.5270 kg/s mass flow rate of the natural gas consumption and the efficiencies of energy and exergy will be 38.34% and 39.76%, respectively. The results examined in the second section, the power produced by the cycle will be 38.4 MW at 0.5270 kg/s mass flow rate of the natural gas consumption and accordingly the efficiency of energy and exergy is found to be 40.011% and 41.763%. Where in the last section, the power produced by the cycle will be 41.43 MW at 0.5270 kg/s mass flow rate of the natural gas consumption and the energy and exergy efficiencies will be 39.76% and 40.924%, respectively. Originality/value The author confirms that this study is original and has neither been published elsewhere nor it is currently under consideration for publication elsewhere.
