Abstract: A comparison of different wind energy collection devices (WECDs) is studied in the highway in order to determine which WECD can collect more wind energy. Firstly, three kinds of WECD are selected for comparison, the self-designed Rectangular turbine (RT), the Banki turbine (BT) and the Combined turbine (CT) which combines both structures of first two. Secondly, the three WECDs structures and parameters are analyzed. The study working conditions are determined which include car and truck driving through the WECD. In addition, numerical simulations of the vehicle and the WECD were performed using Star CCM + software to determine the power coefficient Cp of the WECD. The proposed numerical method need to be validated. The simplification of the vehicle model is verified to be very suitable by comparing it with experimental data. The WECD model is verified by a small experimental model in the condition of similarity of Reynolds number. The results show that the order of the maximum Cp generated by the WECDs is CT > RT > BT. the Cp of the CT is the highest for both cars and trucks moving in the highway. The maximum values are 23.9% and 24.2% respectively.
