The vertical wind array commonly used in threedimensional wind measurement technology has defects in eliminating the shadow effect. This paper designs a nonorthogonal wind array based on special tetrahedron edges according to the characteristics of flow field. The array is designed to reduce the influence of wake region turbulence on the mean wind velocity of the wind path, and to compensate the wind path which the round flow interferes severely. The wind array is modeled with GAMBIT software, and the flow field of gas velocity and Reynolds number of different environmental parameters are changed in FLUENT software to simulate the different performances of the two arrays in the low velocity laminar flow region and the high velocity turbulence region. The cloud chart of velocity distribution and the velocity line graph based on the path of three groups of transducers are obtained to prove that the nonorthogonal array can improve the accuracy of the threedimensional wind measurement.
