Aerodynamics Analysis of Several Typical Cars

详细

During the process of car movement, the air will cause some resistance to the car, and the resistance will increase rapidly when the speed increases. The aerodynamic characteristics of the car will affect the power, economy, handling stability and comfort during driving. Therefore, reducing the aerodynamic drag of the car is an important prerequisite for improving the overall performance of the car. By using the computational fluid dynamics (CFD) software, the dynamic model of different cars in the process of driving is established and the numerical simulation is carried out to get the distribution diagram of velocity, pressure, resistance, lift, and so on. Through comparison and analysis of different car models, the optimized car is designed to improve the aerodynamic characteristics, and it is of great value in the application of the automotive field.
