Thixotropic fluids are fluids that become thinner over time under the continuous influence of mechanical forces (shear stress). This effect is based on the destruction of the structure of the fluid, due to which small interactions occur between the particles. Mechanical forces can be, for example, stirring, kneading, shaking or pumping. Only when the acting forces are suspended do they [...]

Heat transfer is about keeping the temperature of the medium constant, increasing or decreasing it during a stirring process. Tanks specially designed for temperature control are used. As heat transfer via the tank wall is often not sufficient, additional heat exchange elements such as stirring coils, heating or cooling candles and other heat exchangers must be used.

Viscosity is the viscosity or viscosity of a liquid or gas. A model is used that consists of two superimposed plates. Between these plates is a substance that adheres to both plates. In our imagination, the substance is divided into parallel layers. One plate is now pulled in one direction, whereby [...]
