A new-style 1ift-type vertical-axis wind wheel with wind collection-shield pattern suitable to arbitrary wind directions iS researched in this paper. With commercial CFD soRware,the characteristics of this wind wheel are analyzed with numerical simulations.The flow field simulations indicate that the wind energy utilization of this new lift-type wind wheel iS much higher than that of a traditional vertical-axis wind wheel.Furthermore.the orthogonal optimization of the new-style lift-type wind wheel is also conducted for its structure parameters.The wind energy utilization comes up to 39%in the case of optimized design.
