Airflow Sciences started improving vehicle aerodynamics on rail cars way back in 1975, and our focus has been to obtain accurate and efficient data to aid in design decisions. Whether we are performing wind tunnel testing or CFD modeling, ASC has the training and experience for projects large or small. Past work for the rail industry includes:

Exhaust Plume Evaluation in Windtunnel

Exhaust plume prediction
