Wind tunnel experiment and CFD Analysis for the wind erosion/deposition around an obstacle standing on the sand

摘要

In this study, the wind tunnel experiment of the wind erosion/deposition around an obstacle standing on the sand is conducted in order to obtain the validation data for CFD analysis. The relationship between wind velocity, mass transport of sand and the distribution of sand depth due to wind erosion/deposition around an obstacle are investigated through the experiment. In the result of the experiment, large wind erosiouns are observed near windward corners of acubic obstacle in contrast to small deposition in other areas. Furthermore, CFD analysis of wind erosion is conducted for predicting and comparing the results of the experiment.
