N2 - A new experimental facility for experimental validation of numerical codes calculating Czochralski melt flow is described. The setup is built to make all the boundary conditions reproducible in a mathematical model. Measurements are focused on the steady-oscillatory flow transition, which is defined by appearance of temperature oscillations measured independently by thermocouples and interferometer. Location of thermocouples is defined according to numerical predictions, which ensures measurements at locations where oscillations amplitude is large. Current state of comparison of experimental and numerical results is discussed.
