Brownian Motions

Java Applet for Brownian Motion

A Java Applet for analyzing Brownian motion of particles in laminar pipe flow is developed which is available at the course web site. The program solves the particle equation of motion including the Brownian excitation

(31)

The Brownian force is simulated as a white noise process with an appropriate power spectral intensity. The flow and particle parameters and time duration and sample size can be specifies. The variance of the particle position is also compared with the exact solution to the diffusion equation given as
