Webexert the first aerodynamic forces on the entry ve- hicle. Knudsen number, Kn, is defined as the ratio of the quiescent gas’s mean free path to the vehicle’s diameter. At the outer reaches of the atmosphere, Iin is large. As long as Kn > 10, the associated aerodynamic forces can be accurately computed by a free-molecular-flow method. Webaerodynamic diameter (PM2.5). The smaller particles contain the secondarily formed aerosols (gas-to-particle conversion), combustion particles and recondensed organic and metal vapours. The larger particles usually contain earth crust materials and fugitive dust from roads and industries.
