    • Temperature Rise in a Verging Annular Die 

      Younes, Georges R.; Giacomin, A. Jeffrey; Gilbert, Peter H. (2015-12-07)
      Plastic pipes, tubes or catheters are extruded by pressure‑driven flows through annular dies. Whereas die lands are straight, the section connecting the die land to the extruder either converges or diverges, converging ...
    • Transport Phenomena in Eccentric Cylindrical Coordinates 

      Gilbert, Peter H.; Saengow, Chaimongkol; Giacomin, A. Jeffrey (2016-09)
      Studies in transport phenomena have been limited to a select few coordinate systems. Specifically, Cartesian, cylindrical, spherical, Dijksman toroidal, and bipolar cylindrical coordinates have been the primary focus of ...
    • Wall Slip Heating 

      Gilbert, Peter H.; Giacomin, A. Jeffrey (2015-01-05)
      When molten plastic is extruded, the upper limiting throughput is often dictated by fine irregular distortions of the extrudate surface. Called sharkskin melt fracture, plastics engineers spike plastics formulations with ...
    • πάντα ῥεῖ (Everything Flows): Motto for Rheology 

      Beris, Antony N.; Giacomin, A. Jeffrey (2014-05-23)
      This historical study deepens the rheologist’s understanding of the motto of The Society of Rheology, of its history, and of its many typographies. The motto “πάντα ῥεῖ” is not verbatim something written or said by the ...
