Aerodynamic character

The accumulation of dry-deposited material occurs both on the canopy and within the leaves. The amount of dry deposition is determined by the air pollution load (air concentration), the aerodynamic character of the site, and the filtering capacity of the recipient (forest tree with or vdthout leaves) (Hicks and Matt 1988). Dry deposition variations are due to differences in forest structure and site. 

The kinetic interpretation of an aerodynamic process, just as any other "explanation of a physical phenomenon, consists of the representation of the observed sequence of states by a purely conceptual scheme. A special feature of kinetic interpretations, however, is the statistical character of these schemes. Each single process which takes place in the given gas quantum is made to correspond to a whole group of motions of the gas model. This is done with the help of the following concluding assertion ... 

The M2UE (Micro-scale Model for Urban Environment Nuterman 2008) is Computational Fluid Dynamics (CFD) microscale model for analysis of atmospheric processes and pollution prediction in the urban environment, which takes into account a complex character of aerodynamics in non-uniform urban relief with penetrable (vegetation) and impenetrable (buildings) obstacles and traffic induced... 

Heat and mass transfer in a spouted bed has not been fully investigated yet because of the complex character of the flow path of the particles in a bed with zones under different aerodynamic conditions [6]. However, Equations T9.15 and T9.16 of Table 4.9 can be used. 

This chapter presents the rotary kiln freeboard aerodynamic phenomena, drawing parallels with fluid flow in conduits. The goal is to describe the characteristics of confined jets that determine burner aerodynamic mixing and, in turn, combustion efficiency, and flame shape and its character. Having described the flow field, the effect of turbulence on dust pick-up from the bed s free surface will also be discussed.
