Acoustic Streaming for process intensification in mini/microfluidics



PI: Xiaofeng Guo

Students: Chuanyu ZHANG (PhD student)

Collaboration: MSC 7057 UMR CNRS Univ Paris Diderot


Figure 1 : experimental images of acoustic induced streaming




Applying acoustic fields in a mini channel containing sharp edge can enhance heat and mass transfer by locally induced acoustic streaming.
