Finite-element studies combining vibro-thermoacoustic modelling with laminar-flow analysis show that even modest acoustic drive levels can double the rate of ethanol release, or alternatively halve the vacuum requirement. Crucially, this enhancement occurs while maintaining low internal fluid pressures and gentle operating temperatures — preserving the sensory profile of the beverage.

A coupled heat-transfer and diluted-species model was used to quantify how ethanol migrates during low-temperature flashing, and how acoustic pre-conditioning alters the local boundary-layer behaviour. The result is a predictable, controllable improvement in effective mass-transfer rate, enabling low-energy alcohol reduction with far greater flexibility than conventional processes.

The core mechanism is now validated in simulation, and the optimisation space is well-defined. The next phase is to extend the work into full device-scale testing and real-flow conditions, with a view toward compact, integrated systems for premium beverage producers.
