The scientists at Lawrence Livermore National Laboratory are testing new drag reduction devices that could one day make large trucks more aerodynamic. The new truck designs will provide trucks more fuel efficiency, possibly saving the trucking industry as much as 10 billion dollars in fuel costs.


Aerodynamic problems can be classified according to the flow environment. External aerodynamics is the study of flow around solid objects of various shapes. tax relief
