A novel hybrid source-tuner stirring allows for an extended working volume in RCs

The oscillating wall stirrer, introduced recently, is a type of mechanic stirrer which, contrary to most common stirrer types, it does not rotate, but it oscillates. It is this kind of movement that enables the oscillating wall stirrer to implement, in a very easy and successful way, a hybrid stirring strategy combining source position stirring together with the normal tuner stirring. The performance of the hybrid strategy is compared to the traditional oscillating wall stirrer technique by means of several performance indicators. We further observe for this combined stirring, a significant increase in the working-to-total volume ratio with respect to the (already high) working-to-total volume ratio of the oscillating wall stirrer alone.
