Numerical study of unsteady features of airflow around the Ahmed body
摘要
Abstract
The airflow around the Ahmed body with 30° slant angle has been simulated using LES. By statistically analyzing the computational results including drag force, lift force and 3D velocity, consulting the data belong to published reference; the computational method has been validated. The key conclusion is that with 0° yawing angle, the unsteady parameters of airflow around Ahmed body with symmetry geometry are not absolutely symmetrical.关键词
