Large wind farms can significantly change the vertical layered structures and some of statistical characteristics atmospheric boundary layer (ABL). The turbulence momentum flux (VTMF) above a farm, which quantifies transport ABL, is important to meteorological simulation power absorption farm. However, we still lack fast prediction model for VTMF. To this end, suite large-eddy simulations (LESs) performed infinite with various turbine positionings. We show that, in outer VTMF normalized by...
Abstract Hilly terrain can significantly change the flow characteristics of atmospheric boundary layer. However, effects hilly with different steepness on turbine wakes remain understudied. To this end, a wind is placed hilltop steepness, and spread wake investigated via large‐eddy simulation. Results show that, above gentle hills, deflects upward crest downward valley, while for steep in way. Through analysis transport mean kinetic energy, it be found that pressure term works mechanisms...
The concentration distribution of urban air pollutants is closely related to people's health. As an important utilization form wind power, rooftop turbines have been widely used in cities. wake effect the will change flow behind buildings and then affect pollutant dispersion. To this end, dispersion building studied via computational fluid dynamics method. actuator disk model idealized cube are adopted turbine building, respectively. study shows that can reduce mass fraction near ground...
