Boiling is a common mechanism for liquid−vapor phase transition and widely exploited in power generation refrigeration devices systems. The efficacy of boiling heat transfer characterized by two parameters: (a) coefficient (HTC) or the thermal conductance; (b) critical flux (CHF) limit that demarcates from high HTC to very low HTC. While increasing CHF has significant impact on system-level energy efficiency, safety, cost, their values water other fluids have essentially remained unchanged...

Nanoparticles have as characteristics super sliding, extreme pressure, self-healing, etc., which can improve the friction reduction and anti-wear performance of sliding components, when used lubricating oil additives. Nano-copper particles a good synergistic effect with other antifriction agents, antioxidants grease additives because their low shear strength grain boundary slip effect, showing better anti-friction effect. However, nanoparticles are prone to conglomerate, this causes...

The superheat degree (SD) is a crucial production indicator in the aluminum electrolysis process. However, due to harsh environment characterized by high temperature, strong magnetic fields, and corrosion industry site, only limited amount of local flame hole video data can be collected for SD identification. Furthermore, as identification becomes more refined, number categories identified increases. increase results similarities between different categories, which presents challenges To...

In blast furnace (BF) ironmaking process, the silicon content of hot metal is regarded as an important index to evaluate stability and quality pig iron. reality, reactions inside BF with features dynamic, nonlinear hysteretic impede accurate mathematical modeling. Data-driven models predict variation tendency through analysis historical data, which have achieved beneficial results. However, existing data-driven are inefficient handle time series specifically. Therefore, this paper proposes a...

Cyber-Physical Systems (CPS) have been widely deployed in safety-critical domains such as transportation, power and energy. Recently, there comes an increasing demand employing deep neural networks (DNNs) CPS for more intelligent control decision making sophisticated industrial conditions, giving birth to the class of DNN controllers. However, due inherent uncertainty opaqueness DNNs, concerns about safety DNN-enabled are also surging. In this work, we propose automated framework named...

Abstract Since the superheated steam temperature system of boiler in thermal power plant is characterized as time varying and nonlinear, it hard to achieve a satisfactory performance by conventional proportional-integral-derivative (PID) cascade control scheme. This paper presents design method adaptive PID for based on inverse model: First, inner loop outer process are equivalent generalized plant. A simplified Takagi–Sugeno (STS) fuzzy model adopted identify By choosing appropriate...

Gas turbine is a complex, strong non-linear and multi-variable coupling pneumatic thermodynamics system. Its typical model in stability studies consists of load-frequency control, temperature acceleration control. A relationship exists among three control systems which affect the rotate speed exhaust turbine. decoupling method proposed inspired by immune system its bidirectional regulation mechanism this paper. The structure controllers designed then algorithm proposed. applied to gas...

Mainstream industrial practice of assembling different flexible wires into the connector is manual due to specifications terminals and wire assembly requirements. Therefore, efficiency production quality rely heavily on knowledge experiences human workers. To reduce labor cost possible errors, this paper presents an adaptive force posture control strategy for automated wiring terminal (WTA). The contact states during search phase insertion are first analyzed then modeled. With analysis,...

The crane can be used for large mechanical equipment of hydro-mechatronic heavy lifting and transfer operations, has been widely in many practical applications such as construction emergency rescue.Although the winch system is one main parts a hoisting device, amounts energies are wasted rather than being effectively during working process.In this paper, potential energy regeneration analysed, reuse performed by following steps.First, an recovery was proposed, based on connection with...
