Abstract: The external flow-field around trucks would be affected by the lateral wind and their longitudinal spacing change when the trucks travel in tandem. In order to analyze the influence, in reference to the Volvo truck, a simulation truck model with scale of 1: 1 was established. XFlow software was used as the numerical simulation tool. The longitudinal spacing ranged from 0 m to 30 m, and yaw angle of the wind variation range was 0 to 20 degree. The simulation results were analyzed from two aspects, drag coefficient change and fuel-saving rate. The results show that the average fuel-saving rate of the following truck is about 22.96% without lateral wind. While at yaw angle of 20 degree of the lateral wind, the fuel-saving rate is only about 7.41%. This suggests that the lateral wind has great influence on the fuel-saving of the trucks traveling in tandem.

Key words: engineering of communications and transportation system, lateral wind, trucks in tandem, fuel-saving rate, drag coefficient
