The results of mathematical and physical modeling of heat transfer in vibrating flows are presented for Bridgman crystal growth with submerged vibrator. The shadow system and computer processing of photographs is used to observe the melt motion in the experiments. Mathematical modeling is performed on the basis unsteady Navier-Stokes-Boussinesq equations for incompressible fluid, The finite element code ASTRA used for calculations. In numerical simulation the calculated instantaneous flows were averaged in time to evaluate averaged vibrational flow. The numerical and experimental results illustrate the influence of the vibration and the crucible arrangement as well as the vibration amplitude/frequency on the averaged vibrational flow.
