Abstract
This paper describes a direct drug delivery system based on a droplet with a fixed volume of water which travels down a capillary tube. In order to study flow field and chemical concentration of the moving droplet, numerical study was conducted using the Navier-Stokes equations and Fickian diffusion of chemical species with moving mesh. A commercial finite-element analysis software, COMSOL Multiphysics, was utilized to obtain numerical solutions. The relation of inlet velocity and molar concentration delivered of the droplet was investigated extensively.
