With the rapid development of society and the increasing number of infrastructure projects, new huge demand for energy emerges, and, in the meantime, enormous resources are being consumed. Overusing coal, oil, and natural gas consumes resources and increases the greenhouse effect, releasing more toxic substances into the ecological environment. Therefore, in the past development process, the pollution problems caused by projects that relied on fossil fuels as power generation was relatively serious. The traditional energy supply model has yet to meet the requirements of current social development. Along with the emergence of green sustainable development, transformation and upgrading of the power generation industry have become urgent issues to deal with. To effectively solve the problem of environmental pollution and achieve green growth, the current society is actively developing clean and renewable new energy to help the power generation industry develop an energy-saving and environmentally friendly sustainable development model. Among power generation projects, new energy power generation projects play an important role. However, new energy is still developing, so the project investment cost is relatively high. Therefore, it is necessary to improve the construction quality of new energy power generation projects through scientific and effective means to achieve the goal of environmental protection during development.

We prepare the black silicon by directly irradiating crystalline silicon with picosecond laser pulse in atmospheric environment. The grating scanning mode is used in the irradiation process and a regular 20 μm × 20 μm square grating are obtained on the silicon surface. The evolution of surface microstructure with the change of scanning speed and laser pulse energy is preliminarily studied. When the pulse energy is 4.78 μJ and scanning speed is 200 mm/s, picosecond laser can achieve drilling a hole on silicon surface, and the hole will become larger as the the number of pulses increases. In addition, laman spectra is measured and results show picosecond laser processing does not change the crystal phase.

The work presented a numerical study on the transient characteristics of under-expanded hydrogen jets from a cylindrical nozzle. The finite-volume solution was adopted in the two-dimensional simulation of high-pressure chocked hydrogen jets, by solving the Navier-Stokes equations for gas phase flow. Numerical analyses were respectively performed over the micro level to characterize the fine structures, and over macro levels to explore the key global parameters of the gaseous jets. Parameterization work was conducted in terms of the microscopic characteristics of jets, such as, the length of jet core, the diameter of jet vortex, and the key global parameters, i.e. the penetration and the steady fuel injection rate. The effects of the injection parameters on the micro-structure and macro characteristics were hence quantified.

Plasma interacting with electrodes is one of the most challenging issues in many industrial applications, such as power-interruption and plasma-metal erosion. Because of the concentration of arc attachments (root) and the voltage drop across the plasma sheath layer, the arc roots consume great amount of energy, which subsequently will increase the local temperature and erode the electrodes. Due to the nonequilibrium condition at plasma sheath, it is very difficult to quantitatively estimate the arc root temperature profile. The recognition of arc roots behavior, like instability and pattern formation, is important to estimate the electrode erosion. The potential drop arising through the sheath (double layer) is nonuniform. Due to thermionic field emission, the strong flux of charge carriers through the sheath will cause instability of the double layer, which weakens the inner potential gradient. As a result, the strong current dependent potential drop features a negative resistance. The existence of negative resistance causes the instability of arc attachments in the forms of immobility and constriction. Their interdependence between local current density and potential drop gives rise to the arc root formation that concentrates the energy into a small spot. Owing to the negative resistance, any perturbation will cause the current density in the sheath to grow to approximately infinity or decay to vanish, namely arc root formation or extinction. Thereby, the arc root instability provides the basis for the dynamic behavior of arc attachments and detachments on the electrodes, which will help to understand electrode erosion and avoid the damage from the arc plasma in engineering applications.

In order to determine the dominant channel of steam flooding in heavy oil reservoir P612 block of CF oilfield, the geological evaluation parameters of five dominant channels of steam flooding, namely permeability, reservoir thickness, sedimentary microfacies, coefficient of variation and interlayer frequency, were determined by combining reservoir static description with development dynamic analysis. According to the development dynamic characteristics, the sand body of the dominant channel was determined and the sample data was extracted. The fuzzy clustering analysis method was used to divide the two categories of the dominant channel and determine the interval value of its parameters. Thus, the geological classification evaluation standard of the dominant channel was established.
