  • Influences of the Arc Chamber Length on the Jet Characteristics of Laminar Plasma Torch

    Laminar plasma jet (LPJ) which is generated by laminar plasma torch (LPT) has more advantages than the turbulent plasma jet on applications, such as materials processing and plasma spraying. The jet characteristics of LPT are influenced by many factors, e.g., the working parameters, plasma torch construction, gas injection angle, and arc chamber length. A lot of research has been done in recent years. However, a better understanding of how the arc chamber length influences LPT's jet characteristics is still required. Thus, this paper aims to study the influences of the arc chamber length on LPT's jet characteristics. The first part mainly focuses on the introduction of the LPT setup we used in this paper, and this setup can switch the chamber length from 67 to 84 mm or 101 mm by adjusting interelectrodes' number from 3 to 5. The second part introduces the methods and equipment used in this paper. The last part is results and discussions. The results show that when the arc chamber length increases from 67 to 84 mm and from 84 to 101 mm: 1) the corresponding arc voltage and working power of the experimental LPT increase 20% and 12%, respectively; 2) the corresponding thermal efficiency increases 30% and 8%, respectively; 3) the corresponding mean specific enthalpy of the LPJ increases 50% and 20%, respectively; and 4) on the one hand, the LPT's jet length increases slightly with increasing the arc chamber length, and on the other hand, it increases first and then decreases with increasing the working gas; additionally, the plasma jet changes from laminar flow state to turbulent flow state.

  • Composition and thermodynamic properties of air thermal plasmas mixed with ablated Copper and polytetrafluoroethylene vapor

    In order to study the characteristic of fault arc in aircraft electrical system, this paper is devoted to calculate chemical equilibrium composition and thermodynamic properties (mass density, enthalpy and specific heat at constant pressure) of reacting mixtures contained by air, Cu and polytetrafluoroethylene at temperatures of 300-3000 K and pressures of 0.02-0.1 MPa and simulate the corresponding arc process. Under the assumption of local thermodynamic equilibrium, chemical equilibrium composition is solved by the method of Gibbs free energy minimization together with Lagrange multiplier. Debye-Hückel corrections are applied to the free energies of ionized species. Thermodynamic properties are obtained by the standard thermodynamic relationships.

  • A Reinforcement Learning Method for Intermediate Point Enthalpy Control in Super-critical Power Unit

    The intermediate point enthalpy is a significant indicator for the steam temperature in thermal power unit, which has a great impact on the safety and economy in power unit. The intermediate point enthalpy control becomes more difficult in supercritical power unit than in subcritical unit because of controlled plant's characteristics of non-linearity, large inertia and coupling between different input. In this paper, a reinforcement learning method using proximal policy optimization algorithm is proposed to operate the feed water following control scheme for coordinated control system in supercritical unit. Experiment indicates that the proposed method can achieve satisfactory control performance compared with feed-forward decoupling control.

  • Microturbine one-dimensional design methodology using supercritical carbon dioxide as working fluid

    Nowdays, the use of alternative sources of energy has gained much importance due to the reduction of fossil fuel reserves. The supercritical CO2power cycle is being used in applications for power generation with different sources of heat including solar. The main components for a Brayton power cycle are those for turbomachinery group. The purpose of this paper is to present the one- dimensional design development of a turbine for a supercritical power cycle using CO2as working fluid. The procedures here presented take into account the design process of a radial turbine due to the small size found in this component for a supercritical fluid.

  • Advanced Adiabatic Compressed air Energy Storage Energy in Air

    The energy produced by renewable sources like solar and wind energy is intermittent and hence there arises a need to store them to balance the electricity demand and supply. This can be achieved by storing the surplus energy produced when the demand is low and supplying the same when the demand is high. In Advanced Adiabatic Compressed Air Energy Storage (AA-CAES), this energy is stored in the form of compressed air. The heat produced during compression of air is stored in Thermal Energy Storage(TES), using phase change material and the same is released for reheating of air to expand it through turbine, thereby making the process theoretically adiabatic.

  • Simultaneous Regulation of Multiple Flow Rates for Power Generation Control of OTEC Plant Using Double-Stage Rankine Cycle

    This research investigates the power generation control of ocean thermal energy conversion (OTEC) plant using double-stage Rankine cycle whose warm seawater temperature varies. As the plant model, a simple dynamic model is used. For the construction of control system, not only warm and cold seawater mass flow rates but also working fluid ones are manipulated, where each mass flow rate is determined by proportional integral (PI) control law. In this research, the concept of simultaneous regulation of mass flow rates in OTEC plant using double-stage Rankine cycle is proposed. In order to verify the behavior of the proposed control system, simulations were conducted.

  • Optimizing the Operating Parameters of the Humidification - Dehumidification Desalination System by Pinch Technology

    This paper presents the results of theoretical study on the humidification dehumidification desalination system. Based on the Pinch technology, the optimum operating parameters of the system have been determined. The results show that, at the same difference minimum temperature in the humidifier and dehumidifier and at the specific spray water and supply water temperatures, the optimum mass flow ratio between the mass flow rate of spray water and the mass flow rate of air has been determined. At the optimum mass flow ratio, the heat recovery rate and the gain output ratio are at highest value. The higher spray water and supply water temperatures, the higher optimum mass flow ratio and vice versa. For a ΔTmin, there is a proper spray water temperature range for the highest system performance. The results also show that the reasonable water temperature for humidification dehumidification desalination systems is about 55-85°C.

  • Controlling the Temperature of Combustion Products in Power Plants

    The paper describes a new method for determining the temperature of combustion products (CP) of fuel used in combined cycle plants (CCGTs) and steam turbine units (STUs) with their own fuel preparation and combustion system. The method is based on the use of reliable reference data on the thermophysical the CP properties for obtaining correlation dependencies of the individual true enthalpies of the Cp components in the form of polynomials. The application of the method of inversion of polynomials made it possible to obtain in explicit form the relation for the adiabatic CP temperature, which is easily extended to theoretical and balance temperatures. Based on the example of CP fuels of three aggregate states, it is shown that the method can be used to control the process of formation of nitrogen oxides in combustion chambers of gas turbine units (GTUs) and boiler furnaces of STU.

  • An adaptive genetic algorithm approach for predicting magnet-ic structure suitable for high-performance permanent magnet development

    Summary form only given. In this work, we present a general overview, analysis and software implementation of a particular AGA, which has been proposed for discovering new RE-free magnetic crystal phases in the context of the EU-H2020 NOVAMAG project. The workflow diagram related to the Modelling Data Elements (MODA) of the magnetic crystal structure calculation based on AGA was shown. In particular, we make use of an AGA, implemented through USPEX and VASP codes, to predict new magnetic crystal phases, where those structures with better magnetic properties for a permanent magnet are selected and analyzed in more detail. Such a methodology has been preliminary compared to well-known experimentally reported properties compounds, showing an excellent agreement. In addition, we show recent results predicted by AGA in CoFe2nX (n=1,2,3,4,5; where X=C, P, Hf, Zr, ...), where we found compounds with many metastable structures which fulfill the initial requirements (negative enthalpy of formation ΔHF<;0, high saturation magnetization μ0MS>1T and non-cubic lattice system) for permanent magnet development.
