Some problems on offshore wind power development in China;

我国海上风电发展的若干问题初探

The development and current status of offshore wind power technology;

海上风电技术的发展与现状

Although offshore wind power is a clean energy,more or less it will certainly affect the environment in the process of the offshore wind farms construction.

介绍了我国风能利用的现状和趋势,提出了在渤海海域大力发展海上风电的建设,指出海上风电虽然是一种清洁的能源,但在风电场的建设过程中多少还是会对环境造成一定的影响,从海上风电场建设的各个阶段着手,详细分析了在渤海海域建设海上风电场对环境的影响。

Characteristic analysis of the upwind scheme;

上风格式的若干性能分析

Because the electrical equations in electrostatic precipitator are analogous to the equations used to describe fluid flow,the downwind scheme in computational fluid dynamics is introduced to solve the current continuity equation in the case of positive corona,and the relevant upwind scheme is applied in the case of negative corona.

由于静电除尘器电场的控制方程与流体力学具有相同的数学形式,所以将计算流体力学中的上风格式应用于正电晕条件下电流守恒方程,将相应的下风格式应用于负电晕情况。

Through comparing different results of simulating shock reflection flow over a forward step using different schemes including Roe and van Leer schemes,the advanced upwind scheme(AUSM+) is fully studied in terms of its resolution and efficiency for shock waves,expansion vaves,contact discontinuities and their interactions.

研究了新型上风格式ＡＵＳＭ＋的分辨率、效率等性能，并用它与Ｒｏｅ、ｖａｎＬｅｅｒ上风格式数值模拟了前向台阶激波反射流动，通过对激波、膨胀波、接触间断及其间相互干扰的复杂波系的模拟对比，分析探讨了ＡＵＳＭ＋格式的低数值耗散、间断高分辨率等特性。

The environment of wind energy on the sea was analyzed from some aspects such as wind speed, depth of water and sea wave.

从风速、水深和海浪几方面分析了海上风能环境,并从风机支撑技术、风机设计两方面介绍了海上风力发电技术的现状及发展方向。
