Electro-osmotically Driven Flow Near A SoilAnimal Body Surface And Biomimetics

The Electro-osmotically driven flow near a soil animal body surface is a basic electrokinetic phenomenon taking place when the soil animal moves in moist soil. The flow in a micro thin layer of water is formed in the vicinity of the soil animal body surface as a result of the electric double layer (EDL) interaction. Such a micro scale Electro-osmotically driven flow plays the role of lubrication between the soil animal body surface and the surrounding medium of soil and reduces the surface adhesion. The present study has attempted to develop physical and mathematical models to describe this natural phenomenon and develop basic numerical strategies for further quantitative solution. A better understanding of such natural phenomena of Electro-osmotically driven flow near a soil animal body surface is an important stage of biomimetics study and engineering product design.
