Abstract
Considering the characteristics of photophoresis in the actual process, the viewpoint that particles in fluids will experience photophoretic lift force is proposed. The force is related to the particle motion with photophoresis but different from the traditional photophoretic force. Analysis shows that there are mainly two factors contributing to the lift force, one stems from the variation in the distribution of light intensity, the other originates from the rotational motion of particles in a direction which is perpendicular to the optical axis. The expression of the photophoretic lift force has been given in the study. The impacts of the force have been analyzed and validated by comparing with previous experimental results.
