Deposition Calculator Software Ver. 2 Beta

Deposition Calculator is software used for evaluating the penetration or transmission of an aerosol through transport system.  The Deposition Calculator version 1.1.1 represents a complete rebuild of the software using an object-oriented design. 

An aerosol transport system is a collection of flow components such as tubes, bends, and probes that allows for the extraction and conveyance of an aerosol sample from one location to another. The term sample line is often used interchangeably with the term transport system. Deposition Calculator software allows the user to analyze a model of a transport system or sample line to determine the fraction of particles of a given size that are conveyed from the system inlet to the outlet, otherwise known as the sampling efficiency or particle penetration. Typically, some fraction of particles will be lost to the walls of the system due to mechanisms such as gravitational sedimentation, diffusion, or inertial impaction. In Deposition Calculator, a transport system is represented by a linked list of components that represent the mechanical elements of the physical transport system. Only transport components that have published efficiency models are represented in Deposition Calculator.  Actual transport systems may contain features or exhibit deposition mechanisms (e.g. electrostatic deposition) that are not modeled by Deposition Calculator.  Failure to accurately model the physical system may lead to prediction of transport efficiency that does not match that of the physical system.
