The Right Mixing Software for Me in 2024

When we’re talking about mixing—like the standard way or by doing some bench marketing—we can find three types of software to help us characterize a specific unit operation—in our case, mixing. The first group of software is based on the pure theoretical solution of flow models into a geometry. So, with this kind of software we will be able to generate the specific geometry, fill this geometry with some fluid, and then apply the main momentum balance in order to solve this kind of environment.

The results are velocity, and from the velocity we can calculate other parameters according to our definitions. An advantage of these kinds of software is that they are based on common theories that are accepted in the academic community; if we want to compare the simulation by itself, these kinds of software should, of course, be very good. The disadvantage is that these types of software are very theoretical, and when we are trying to catch the specific geometries and specific phenomena that are happening today, the specific equipment will, in our case, be the sterile vessel. These kinds of software are purely theoretical and sometimes far from the description of what really happens in the sterile vessel.

The second type of software is based on a very simple concept: pure empirical data or correlations. These kinds of software are simple to use; we only need to feed the data, and immediately we get results. The advantage of these kinds of software is that they are really connected to real life and not only theoretical environments; but the disadvantage is that the physical models are not taken into consideration. If the empirical correlation we use is far from the equipment that was the source for these same correlations, normally we will have deviation.

So, we need to be sure that our equipment will be similar to the equipment that was used in order to generate the correlations.

The first group of software that is only one type—that is, VisiMix—is a combination between them. We solve the momentum balance to know the velocity of the flow, and we use numerical methods in order to solve it according to our model of a mixing into sterile vessels. We use empirical data that we collect during our research and development, but when we talk about the correlations, they are not correlations that were only in the literature; they are correlations that go very deeply in the fundamental of flow dynamics and flow mechanics.

So, for instance, if we’re trying to connect between the friction factor and the Reynolds number in the sterile vessel, where we have a radial impeller or action impeller without buffers or with buffers and for every kind of configuration, we generate a model. The basic principle of this model is that we’re taking in consideration the central part of the tank close to the impeller and the peripheral part of the tank far from the impeller. The criterion to decide between the central part and the peripheral part is the main circulation flow direction that we have in the tank. Internally or externally, we’re using diffusivity, fluid flow diffusivity, according to the main theories and the turbulence ratio.

So, for me of course, the right mixing software for the industry that is fast, based on phenomena that we catch during our investigation and development of the software in a sterile vessel, is VisiMix. We invite you to use VisiMix, prove its effectiveness, and enjoy the extensive customer support provided with it—the main intention of which is to provide the customer an understanding of the field of mixing and the pure mixing parameters and specific process they’re running in a company.
