MASS DIFFUSIVITY MEASUREMENT SYSTEM

摘要

Methods and system for measurement of mass diffusivity are described herein. In one implementation, a diffusivity analysis system (100) includes a diffusion cell (112) containing a binary diffusion system (136), a light source (102) to radiate a parallel beam of light (108) to pass through the binary diffusion system (136), and an image capturing device (130) to capture an image of light streak at several instants of time. The diffusivity analysis system (100) also includes a computation system (132) to process the captured images, and compute the mass diffusivity of the solute based on the position of the light streak in the images.
