WebbThermophoresis هنگامی که یک شیب دما در یک گاز وجود داشته باشد، ذرات معلق تمایل دارند از مناطقی با درجه حرارت بالا به پایین منتقل شوند. نیرویی که این اثر را ایجاد می‌کند، نیروی ترموفورزی نامیده می‌شود. 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.
