The paper is devoted to a study of metal melt flow pattern in the through-flow metallurgical aggregate (tundish) under different boundary conditions. For evaluating of flow conditions in the tundish a permanent concentration change (Heaviside unit step) was used. Experiments carried out by physical model in the geometric scale 1:5 to the real tundish and simultaneously carried out by numerical simulations...
This paper is concerned in modeling of noise propagation of a small end-fixed plate. The excitation was harmonic in range of audibility region. The modeling of noise propagation is made in MATLAB r.6. The noise propagation is calculated in ANSYS 5.7 because of comparing. The analysis of size of acoustic field in effect on a sound pressure level in case of model without boundary elements in the border...
