Abstract:The environment surrounding us is composed of aerosol particles, which can be radioactive, allergic, or therapeutic in nature. Toxic particles when deposited on the respiratory tract may lead to the pathogenesis of lung disease. On the other hand, therapeutic aerosols are used for many respiratory diseases. Moreover, long term space travel and associated risk of inhaling hazardous nonterrestrial aerosol have made it significant to study the impact of gravity on particle deposition. Accurate deposition prediction is prerequisite for both toxicity measurement and drug delivery. Lung deposition of aerosols may be a very sensitive time dependent phenomenon. So to capture the true effect of time-dependency and to predict the transient local deposition, functions based on instantaneous deposition rate are required. An attractive alternative is to develop a numerical scheme that gives a better agreement with experiments using the existing functions. In the present study two such schemes will be described and implemented in an Eulerian deposition model (TECHAero) to predict some practical cases.
