Computational aerodynamics analysis of a bluff body with rotating cylinder as drag reducer

This study is aimed to address the issue of dangerous emissions into the environment by the operation of large container lorries. These big vehicles use much of their engine power to overcome the aerodynamic drag due to their movement, which also means a lot of fuel is being burned in this process....
