✦ Synopsis

The first quantitative description of melting in single screw extruders was given by Z. Tadmor around 1965. A simple analytical theory was developed for Newtonian fluids, assuming thefluid viscosity to be unaffected by changes in temperature. Also, an approximate analytical theory was developed for a power-law fluid, assuming the power-law constants to be independent of temperature and viscous dissipation to be negligible. Later workers extended the theory, however, most of these extensions did not allow closed-form analytical solutions, thus requiring numerical techniques to obtain solutions. One of the most crucial assumptions in the

The simpk ~~11 theory of dense simple liquids, based on irregularly arranged cells, is exrended by allowing the atoms in a11 the cells to bchavc in the same fashion as the "reference" atom. It is shown that such a modification leads to two widely different sets ot rherrnodynamic predictions, one of
