Front-end airflow predictions are generally carried out at the styling stage in the development process for vehicle cooling systems. These predictions have taken on increasing importance in recent years in studying the heat radiation capacities of the radiator. This paper presents a method for simulating front-end airflow rates. Two- and three-dimensional front-end airflow simulations are first analyzed experimentally. A technique for predicting a three-dimensional airflow from a numerical analysis of a two-dimensional airflow is then examined, and a comparison is made with actual vehicle data. A sample application of this simulation method is presented and a comparison is made with experimental data. Good quantitative agreement is seen between the calculated and experimental results. This paper also discusses the present status of three-dimensional analysis which is expected to become a major trend in the future.
