摘要:

The airflow around a simple automobile shape is calculated using a distributed source–sink technique. This is then used to determine the trajectories of snowflakes, and it is shown that, for a given snowflake size, there is a range of travel speeds that minimizes the impaction of snowflakes on the windshield.
