WebbThe Thermophoretic Force accounts for a force on a particle due to gradients in the temperature of the background fluid. The thermophoretic force is defined as: where • k … WebbWhen 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.
