Installation height analysis of Ф-type vertical axis wind turbine on the flat building

摘要

In this paper, we simulate the wind environment of a flat building without wind turbine by using FLUENT software. From the perspective of turbulence intensity and wind speed ratio, the wind turbine's install heights of front edge, middle and back edge at flattened building are determined; and then wind turbines are installed at the forefront of building to simulate the flattened building wind environment. In the case of considering the front wind turbine producing wake, the installation height of middle and back edge wind turbine will be further explored. The best position and arrangement of wind turbines on the flat buildings were also discussed. What's more, the utilization efficiency can be analyzed.
