Quantum Electrodynamics and Casimir Effect

We investigate the effects of transverse flow on Bose-Einstein correlations by using an exact three-dimensional solution of the equations of hydrodynamics. Contrary to what one might expect it is found that transverse flow does not increase the transverse radius. On the other hand, a strong dependence of the longitudinal radius on the transverse expansion is found.
