Investigation of T Shape geometry for the collectıon of pollutıon partıcles

Abstract

The study of suspension flow is of considerable importance in many fields of science and technology. Particle pollution, for example, has become a main issue of our days due to harmful aspects associated. For rational air pollution, sampling devices are essential. In this work, we numerically investigate a three dimensional T-shaped device that can be used for aerosol sampling or Lab-On-a-Chip (LOC) devices. Two key quantities are used to characterize the suspension flow: Particle deposition and residence time distribution of the particles. This study clearly demonstrates that the geometric characteristics of T-shaped structure and the Reynolds number should be closely controlled in order to obtain the required particle deposition and dispersion of particles inside the T-shaped structure.
