Abstract
This study aims to clarify the cedar pollen transportation by suspension and saltation and to confirm the validity of the prediction method. For this purpose the followings are done: (1) The terminal velocity of Japanese cedar pollen is measured and the test particle is selected. (2) The suspension and saltation behavior of the test particle is observed and measured by the optical measurement methods: path line image analysis and particle tracking velocimetry. (3) The suspension and saltation behavior is also numerically calculated by Euler-Euler method and Lagrangian particle tracking method respectively. These methods can predict the suspension and saltation behavior.
