[1]. CBNP Transport & Fate Team, http://www.lanl.gov/orgs/d/d4/pdf/air/model_review.pdf accesed May 2007. (Chemical & Biological Nonproliferation Program) had been classified become five-types of computer codes that already used in the world to modeling transport and fate phenomenons, i.e.,: CFD Models for Flow around Building, Building Interior Flow and Transport Models, Mesoscale Atmospheric Models, Plume Dispersion Models, and Subway System & Interior Flow Models.

[Examples of CFD Models for flow around buildings are: Dynaflow, FEM3C, GASFLOW, HIGRAD, and TEMPEST.
Examples of building Interior Flow and Transport Models are: COMIS, MIAQ4, CONVECT9, GASFLOW.
Examples of Mesoscale Atmospheric Models are: COAMPS, HOTMAC, NORAPS, RAMS.
Examples of Plume Dispersion Models are: ADPIC, HYPACT, LODI, RAPTAD, SALB.
Examples of Subway system & Interior flow models: GASFLOW, SES.]

[2]. Sohn, et. al. (2004) already reviewed many existing technologies that could protect the supply air systems of buildings from chemical/ biological (chem/bio) contaminants such as FEM3MP, HPOC, CONTAM, dan FLOVENT. FEM3MP and HPOC for external dispersion modeling, CONTAM and FLOVENT for internal dispersion modeling. The results provide a modeling approach that can be used to simulate the dispersion of contaminants inside buildings. Such a numerical simulation will help designers and managers evaluate possible ways to reduce occupant exposures to chem/bio contaminants.

[3]. CFD is a mathematical modeling procedure whereby the fluid parameters of velocity, temperature, pressure, turbulence, and contaminant concentrations are calculated by solving the governing partial differential equations for fluid flow, heat transfer, and conservation of species. These differential equations describe a threedimensional viscous fluid flow field. Due to the non-linearity of these equations, they cannot be solved analytically. The CFD approach is to transform these differential equations into a set of discrete algebraic equations and solve the algebraic equations by an iterative procedure.

[6] Sippola and Nazaroff (2002), describe four broad methods of predicting particle deposition rates that found in the literature: empirical equations, Eulerian models, sublayer models and Lagrangian simulations. These methods usually require information about the particle size and density, as well as the air speed and dimensions of the duct containing the flow. Deposition rates are most commonly reported in the form of the dimensionless deposition velocity, Vd+, versus the dimensionless relaxation time, τ+, a measure of particle inertia.
