Abstract

There is a global interest in renewable energy resources such as wind energy. INVELOX is an innovative. Some research has been performed to improve the efficiency of this machine by various geometrical modifications. Two new ideas are numerically analyzed in the present research to study their effects on the wind velocity when approaching the wind turbine, and consequently, on the wind turbine efficiency. In one of them, a relatively long flange is added to the original design, and in the other one, a pair of holes are considered in the venture to try to increase the mass flow rate of wind when reaching the turbine. Three various sizes of holes are studied here. The results reveal that using the long flange leads to an increment in the maximum wind velocity (about 15.45%) and more than 176% increase in the harvested power. In addition, the pair of holes in the venturi with a diameter of 35 cm results in a slight improvement in the harvested power. For the first time, the turbine has been modeled inside the venturi. A comparison between the results for the INVELOX, including the turbine, and that of the turbine in the free stream indicates that implementing INVELOX leads to 3.14 times more power generation.

INVELOX风力机的创新设计:采用长翼缘和文氏孔的数值研究

全球都对风能等可再生能源感兴趣。INVELOX是一家创新型公司。已经进行了一些研究，通过各种几何修改来提高这台机器的效率。在本研究中，对两种新的想法进行了数值分析，以研究它们对接近风力涡轮机时风速的影响，从而对风力涡轮机效率的影响。在其中一个项目中，在最初的设计中增加了一个相对较长的法兰，而在另一个项目，在风险投资中考虑了一对孔，以试图增加风到达涡轮机时的质量流量。这里研究了三种不同尺寸的孔。结果表明，使用长翼缘会使最大风速增加（约15.45%），收获功率增加176%以上。此外，文丘里管中直径为35cm的一对孔导致收获功率的轻微改善。首次在文丘里管内对涡轮机进行了建模。包括涡轮机在内的INVELOX的结果与自由流中涡轮机的结果之间的比较表明，实施INVELOX可使发电量增加3.14倍。
