Brownian motion in base fluid

WebFeb 1, 2015 · Thermophoresis is an interesting consequence of the Brownian movement of particles in fluids with an externally sustained and constant temperature gradient: It becomes apparent from Eqs. (1), (2) that particle dispersion is higher and the Brownian force is stronger when the local fluid temperature is higher. WebBrownian motion is the random, uncontrolled movement of particles in a fluid as they constantly collide with other molecules (Mitchell and Kogure, 2006). Brownian motion is in part responsible for facilitating movement in bacteria that do not encode or express …
