hi Marshall and SOWFA enthusiasts,
I used SOWFA to study the wake of wind turbines. I calculated the conditions with six wind turbines. The six wind turbines were arranged in two rows(as shown in the figure below). The pre-simulation time is 20000s, and the wind turbine simulation time is 4000s. The incoming wind speed is 8m/s. Most of the other parameters are set using the values given in the case. I took the result of 1200s after the calculation time to calculate the time-mean streamwise velocity. There is a strange phenomenon in all the calculation results. The inflow wind speed of the wind turbine near the inflow position in the top row is significantly lower than that in the bottom row (as shown in the figure below, the short black lines represent the wind turbines). Can anyone explain this phenomenon?
Thank you for your help,
Liu Mingqiu
