Design and simulation of simple miniature devices for differentiation of airborne particles

With the invention of the cascade impactor in the 1970s, coupled with the application of high-speed computers and finite difference methods, a deeper understanding has been developed with regards to the flow field and particle trajectories within impactors. Extensive studies in the 1970s have shown...
