We studied the air-liquid interface behavior in the microstructure of the wall surface by the numeric simulation. Level set method was used for an analysis of air-liquid interface. For hydrophobic surface, it was clarified that an air layer keeps its shape in the microstructure at the flow condition. On the other hand, the liquid penetrates in the microstructure when the surface is hydrophilic or velocity is fast even in the hydrophobic surface. In addition, from the analytical result using the proposed model which alternately applied slip and no-slip boundary condition to the wall surface, it was clarified that the drag reduction effect is dependent on not only Re number but also the channel height and the length of the slip boundary condition.
