Numerical simulation of axisymmetric non­Newtonian free surface flows

A numerical method for solving axisymmetric transient non­Newtonian free surface flows is presented. The methodology employed is an extension of the two­dimensional GENSMAC code, employing a marker­and­cell technique and solving the governing equations using finite differences approximations on a staggered grid. Marker particles are used which provide both the location and the visualization of the free surface. Several simulations demonstrating the differences between Newtonian and non­Newtonian flow are presented.
