FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy. Simulation is performed by feeding water into mould model with glass walls at ambient temperature and mould walls temperature of 10-15°C. Inner surface of mould model walls is blackened to apply LC-layer of cholesteryl erukate. Water fed into model is heated to 40-43°C and held therein to 20-25°C to produce colour image by light diffraction at periodic structure of cholesteryl erukate. Then, image is registered by video camera and transmitted to computer display. Water flow rate in model is set equal to ωm=0.4-0.6 m/s. Length 1 of model wide wall is defined using criterion of similarity of Reynolds number Re=ωm·1/ν=(0.16-0.36)106, where ν is water kinematic viscosity.
EFFECT: higher efficiency.
