Abstract
The influence of higher harmonic generation due to acoustic nonlineari ty on the rise-up profile of acoustic streaming is investigated. When two driving conditions with different higher harmonic content at ident ical driving force are set, the behavior of streaming under these cond itions is experimentally compared. A thin film is used to eliminate th e influence of acceleration. It has been believed so far that streamin g rises more quickly as the generation of higher harmonics increases. However, the present analysis concludes that the rise-up profile of ac oustic streaming is dependent only on the driving force and is indepen dent of the relative higher harmonic contribution to the driving force .
