VisiMix is the first and the only software developed by highly qualified mixing professionals. The VisiMix development team includes world renowned scientists with more the 100 years of combined experience in:
-research and mathematical modeling of mixing, and heat and mass transfer;
-development of new processes and equipment for different branches of the chemical and process industry
-designing, testing, manufacturing, and operating of all types of industrial mixing equipment
VisiMix is the first and only software product that, together with local and average characteristics of flow, provides complete information on mixing, heat and mass transfer parameters that are directly connected to the object and purpose of each process.

VisiMix is the first and the only mixing software that for more than 15 years has been used successfully by many leading chemical and machinery companies worldwide (DOW Chemicals, Pfizer, DeDietrich, Teva, etc.).
Our Costumers
Only VisiMix customers obtain technical support provided by a team of chemical and physical engineers that includes world renowned professionals in mixing, process, and equipment development.
Our Team
VisiMix supports the modeling of mixing with impellers of any industrial design. A complete set of dimensions and angles of the blades is required for an exact simulation. If such data are not accessible, VisiMix provides recommendations for the approximate input that would result in an acceptable degree of accuracy of the simulation.
No additional knowledge is needed to use the VisiMix software, and the simulation is easily accessible to any engineer. To become acquainted with user interface of the program, we recommend downloading the free version of VisiMix

Specify a tank with an elliptical bottom. The difference does not affect mixing and can be neglected for the purpose of calculations and modeling.
Enter an equivalent angle (EA) estimate: EA = (180 – CA)/2.
For example, real CA = 150 degrees. EA = (180-150)/2 = 15 degrees
If flow is turbulent, a significant change in local temperature occurs at the boundary layer, but only along the heat transfer surfaces. VisiMix provides the values of the temperature on these surfaces in the HEAT TRANSFER sections.
Differences in local temperatures for the bulk of mixing reactors in a turbulent regime are always below the boundaries of practical importance. This is because the heat conductivity of liquids is about 1000 times higher than diffusivity, and the maximum rate of local heat release cannot be too high because of the turbulent mixing. These results are in complete agreement with the mathematical models used by VisiMix. At some point in our research we conducted a special study on this topic, and we were able to achieve a measurable difference of local temperatures only in experimental mixing vessels of a very special design.
For all practical purposes, temperature in bulk of reactors in a turbulent mixing regime can be treated as uniform.
Yes, it is. In laminar a regime, the power consumption for each ribbon can be calculated independently. The same rule can be used for an approximate calculation of the flow capacity of each ribbon.
The number and width of radial arms are defined by the designer based on mechanical calculations.
VisiMix supports for 1 to 4 ribbons with a pitch ranging from 0.5 to 2 diameters. This covers the range of helical ribbon applications, within their practical limits.
The design and diameter of shaft are determined by the designer. VisiMix provides options for mechanical calculations of shaft torsion and vibrational stability.
VisiMix can be used with laboratory mixers, including magnetic ones. In the case of the usual magnetic mixers the modeling is approximate because of the “zero” distance between the impeller and the bottom of the tank.
In a turbulent regime, the helical ribbon can be treated as an anchor agitator with the same width, number, height, and tip diameter of blades.
