Ali Abdulkadir Aden | Su Bo
Abstract: The integration of wind energy utilization and high - rise building design is the combination of advanced building technology, energy utilization, and wind energy generation. This integration transforms the structure into a wind energy carrier. This topic focuses on how to increase wind power generation by using building design techniques to turn high - rise building into wind concentrators in order to increase wind power generation. The primary research works on the influence of fundamental high - rise buildings architectural forms on wind energy use are as follows. Firstly, the evaluation indexes of wind resources and wind resources in the built environment were presented, as well as the general laws of the distribution of wind resources in the built environment and evaluation indicators of building wind energy utilization efficiency. Secondly, based on case collection and literature reading, a basic form that facilitates the use of wind energy in a high - rise building is systematically summarized. A brief introduction to a high - rise building with an opening through architectural form suitable for placing wind energy harvesters of wind generators. Thirdly, the choice of CFD software is introduced. Then, using Fluent to numerically simulate the wind resources of two kinds of super high - rises, analyze their influencing factors on wind energy utilization. Finally, an experimental study on a newly developed wind - induced galloping energy harvester has been conducted. In the CFD results we can see the location with higher wind speed and lower turbulence intensity is suitable for the installation of wind - induced energy harvester. (1) The wind speed enhancement effect of the wind passage is related to the design height of the air passage and the shape of the inlet as well as the appeal factor. (2) The wind speed strengthens the effect is obvious, when the installed height of the wind - induced energy harvester is 3?4 of the total height and the shape of the inlet is an arc.
