The article describes the implementation of visual simulation of melt jet movement. The urgency of the work connected with necessity of debugging of the algorithm for melt jet flow rate estimation, which provides permanent control of the melt consumption. It allows to monitor the centrifuge and ensures specific parameters of the mineral wool carpet. Main adjustable parameters of the mathematical model, such as melt temperature, outlet size and geometry, pressure value, kinematic viscosity, melt density and frequency of the mechanical influences on the melt stream are listed. It is stressed that the development and visualization of the mathematical model allow to set the varied initial conditions that leads to decrease in the production costs for carrying out experiments and testing the algorithm. In addition, 3D model provides clarity of the experiment.
