An Examination of the Resonant Acoustic Mixers Flow Field
Abstract
This report details a second step made toward the high fidelity, first principles numerical simulation of the mixing for the resonant acoustic mixer. The current study addresses the mixing of two resins at higher, differing viscosities. Of interest is the time accurate vortical structure of the mixing flow field. As a matter of post-processing, the progression of eddy sizes is determined by wavenumber transformation. The computer code of choice employed in this study is LESLIE3D (Large Eddy Simulation with LInear Eddy modeling in 3 Dimensions) developed under grant by Suresh Menon at the Georgia Institute of Technology. Although LESLIE3D is not directly adapted for this problem, the code is imminently changeable. LESLIE3D has been modified to produce the acoustic excitation required for the mixer. In this case, we scale the viscosities in the transport algorithm to more closely mimic those of the actual resins. The results for a two-components mixing case are presented along with the ensuing wavenumber analysis.
