| 内容記述 | As a tentative estimate, we made a simple model of simulating erosion by wind using a sand transfer equation and we could reproduce a process of formation of a strange shaped rock. The numerical method is as follows: First, flow field around a rock which is governed by incompressible Navier-Stokes equations is solved numerically by the standard MAC method. Second, we estimate amount of erosion that is proportional to the cube of friction velocity. Third, new shape of an eroded rock is calculated. These three steps are repeated. The flow around a rock and its surface are visualized and the influences of hardness of the rock on erosion by wind have been analyzed. Moreover, we examined several typical cases in order to reproduce strange shaped rocks appeared to Cappadocia in Turkey. | |||||
