Abstract

Multiflash photography is a simple, economic, and efficient technique for the research of desert physics. The study of the micro-characteristics of sand blown by the wind in the desert is one of the basic subjects in desert research. The research on this gas-solid two phase flow was conducted using high speed multiflash photography both in the environment sand wind tunnel and in the natural desert environment for studies of the flight trajectories of moving by jump of sand grains and the structure of wind-blown sand. The experimental results indicate the moving trajectories of sands by wind presents the form of opposite parabola. The taking- off angles have linear relation with the descending angles. The distribution function of the sand content of the wind-blown sand is verified through the statistical analysis.
