justify;text-justify:inter-ideograph;line-height:normal">Inspired
by animal digestion systems, a new soft-elastic reactor (SER) has been
developed in our group^[1]. Different from convectional reactors,
this type of reactor contains no separate moving parts inside the container and
mixing can be achieved through elastic wall movement. SERs potentially have
some advantages over conventional rigid wall reactors especially when dealing
with highly viscous or corrosive fluids.

justify;text-justify:inter-ideograph;line-height:normal">In
this talk, we will introduce the prototype of this new reactor, specifically
focusing on an image analysis based method developed for quantitative evaluation
of the mixing performance of SER^[2]. The source data collected are
RGB values in each pixel of consecutive colour images taken by a CCD camera.
The method can determine global indicators such as the mixing time and the average
mixing level, " times new roman>i.e., the degree of homogeneity, uniquely
characterized by the “distance” away from the ideally mixed state. More
importantly, it allows tracking of localized mixing performance throughout the
entire mixing process by quantifying spatial and frequency-domain distributions
of the mixing level. This simple, generic, and cost-effective method should be
a powerful tool for mixing performance evaluation of most reactors with a variety
of mixing mechanisms. Furthermore, based on the introduced method, improved designs of
SER have been identified, which will also be discussed in this talk.
