Abstract

We washed a solid surface (SUS304) attatched with starch paste as the soiled model because of investigating washing effect of fine bubble mixtures via high swirling method and pressurized dissolution method, respectively. As compared with water one, relative high washing effect of microbubble mixtures was observed. Furthermore, good agreement between the resultant wasing rates of high swirling method and those of pressurized dissolution method was obtaind. For understanding the experimental results, particle diameter change and static contact angle of interface between test fluids and solid surfaces was measured and discussed.
