Dynamic response analysis of wind turbine plays a pivotal role in their analysis, design, stability, performance and safety. To improve the calculation accuracy of natural frequency and dynamic response of megawatt wind turbine flexible components, a novel time-variant prediction model which can...

Direct numerical simulation (DNS) is used to study spray combustion in a slab layer configuration. The gas phase is simulated in an Eulerian way, while the droplets are tracked with a Lagrangian method. The coupling between the two phases is considered. A fourth-order explicit Runge–Kutta...

Doping the carbon-free fuel NH 3 into pulverized coal furnaces is a feasible approach for reducing CO 2 emissions during thermal power generation, but the NH 3 co-combustion increases NO x emissions. Therefore, it is necessary to study the formation mechanism of NO during the NH 3 -pulverized...

The present work introduces an approach to predict the nitrogen oxides (NOx) emission characteristics of a large capacity pulverized coal fired boiler with artificial neural networks (ANN). The NOx emission and carbon burnout characteristics were investigated through parametric field...

The performance of a parabolic trough collector (PTC)-based steam generation system depends significantly on the heat losses of the solar receiver. This paper presents an experimental study of the heat losses of a double glazing vacuum U-type solar receiver mounted in a PTC natural circulation...

Considering the necessity of green and sustainable recycling of spent lithium-ion batteries (LIBs). Herein, a green closed-loop leaching process based on electrolysis of sodium sulfate solution for recycling spent LIBs is demonstrated. The sulfuric acid and sodium hydroxide obtained by...

Culture is the core factor of corporate innovation, and board culture is the core embodiment of cultural factors in corporate governance. Board culture will have an important impact on corporate innovation, So what kind of board culture can Chinese boards build to better contribute to corporate...
