Diffusion Model of Drug Concentration and Application in Industrial Design

摘要

the diffusion model of drug concentration is constructed using pharmacokinetics, initial conditions and boundary conditions. Item z is fixed at a certain value while the concentration is expressed as a function of radius and time, basically decreases along the radial direction and increases over time. Moreover, concentration diffusion in the radial direction is subjected to vascular wall constraints with on z on infinite boundary, while concentration diffusion in the axial direction propagates in ellipsoid. At last, this paper discusses its application in industrial design.
