Peripheral flow and coordinate system
Grahic Jump Location
Schematic of the cross section of the core
Grahic Jump Location
Core shapes for negative Eötvos numbers. For Eo=0 the core is a circle; then it deforms progressively as Eo increases. The horizontal segments represent Eq. (18).
Grahic Jump Location
Eötvos number Eo as function of the parameter E*
