Subject and Keywords:
Under the assumption of quasi-elongational approximation, i.e., for uniform velocity profiles across the filament, melt-spinning processes as well as film casting and drawing processes are treated as particular cases of flows with dominating extensions. Certain approximate solutions for slightly non-Newtonian fluids and under the assumption of nearly extensional and weakly nonisothermal flows are discussed in greater detail. Two types of boundary conditions are considered on the free surface of the thread: the first resulting from the force balance, and the second determined by the vanishing radial stress component.
