Abstract

In this investigation, the shape and the amount of swelling were measured for several Newtonian and viscoelastic fluids. The effect of the gravitational body force was investigated systematically. In the case of Newtonian jets, experimental measurements were compared with numerical solutions obtained by a combination of finite-element computation and analytical solution. For viscoelastic jets, the fluids was a carefully characterized Boger fluid. Experimental data were compared with finite-element solutions reported in recent literature for Oldroyd-B fluids.
