Computer Simulation Helps Design High Efficiency, Low Pressure Drop Pre-Cleaner

摘要

Donaldson engineers set out to design an air pre-cleaner product line for off-high way vehicles that extends air filter life and improves fuel economy by providing higher separation efficiency and lower pressure drop than existing designs, now named TopSpin~(TM). The design utilizes vanes moving faster than the flow to produce a positive pressure wave that force inertially separated particles out of the pre-cleaner. Designing this product line in a traditional manner would have required building and testing many prototypes in order to determine the dimensions of each component that provide the best performance.
