Abstract

In this paper, Large eddy simulation of a two-turbine system is implemented, with the upstream and downstream wind turbines operating at yaw angles equal to 200 and 00 respectively. A second case (baseline case) is simulated, in which the rotation planes of both the upstream and downstream turbines are perpendicular to the mean flow direction. Realistic turbulent inflow is fed to the wind turbine domain from a precursor atmospheric boundary layer simulation using spectral interpolation techniques. An analysis of the effect of yawing on the wake of the turbine, through streamwise velocity, variance and kinematic shear stress profiles at multiple downstream stations, has been presented. A comparison of the overall Coefficient of Power of the two-turbine system, between the yaw case and the baseline case, is also carried out.
