摘要：

The steady, nonuniform, axially symmetric, extensional flow characteristic of a molten threadline was investigated. Most attention was given to incompressible isothermal cases. Approximation procedures based on the gradient of the thread line diameter being small were developed: These make the problem one-dimensional. Specific solutions were obtained for Newtonian and Coleman and Noll second-order fluids. The relevance of a generalized Trouton viscosity model is analyzed. Possible extensions to nonisothermal flows are discussed. © 1969, American Chemical Society. All rights reserved.
