When a temperature gradient in a gas exists, suspended particles will tend to move from regions of high temperature to low. The force which produces this effect is called the thermophoretic force. Gas molecules colliding with a particle from the hot side have a higher velocity than the cold side, which results in a net force towards cold areas. This effect can be exploited to create thermal precipitators which can filter out undesirable particles from a feed gas. It can also be used in chemical vapor deposition, to inhibit the arrival of particle contaminants on the surface of a susceptor. This model simulates the size of a particle-free zone above a heated susceptor for different temperature gradients.

This model requires the Particle Tracing Module and the Heat Transfer Modules.
