Computational Analysis of Non Spherical Particle Transport and Deposition in Shear Flow With Application to Lung Aerosol Dynamics—A Review

Abstract

All naturally occurring and most manmade solid particles are nonspherical. Examples include airpollutants in the nanoto micrometer range as well as blood constituents, drug particles, and industrial fluidparticle streams. Focusing on the modeling and simulation of inhaled aerosols, theories for both spherical and nonspherical particles are reviewed to analyze the contrasting transport and deposition phenomena of spheres and equivalent spheres versus ellipsoids and fibers.
