Abstract
Wiper is an important vehicle equipment to keep a clear view for a driver. The characteristics of the fluid flow around the blade lip of a wiper have been discussed in this study. The analytical model for the fluid flow and the governing equations for the model have been established. The governing equations have been numerically solved. It is concluded that there is a relationship between the water film thickness and the blade angle and the size of the gap. Moreover, meniscus force around the outlet of the gap will be considered.
