The isobaric thermal expansion coefficient ( 0) was determined experimentally as a function of temperature for two non-Newtonian fluids: water solutions of CMC 7H4 at 5000 parts per million by weight (wppm) (purely viscous fluid) and AP-273 Separan at 2000 wppm (viscoelastic fluid). The temperature range was approximately 25-55° c theological flow curves were also measured during the experimental sequence. The expansion coefficients for the non-Newtonian fluids agreed with those for the pure water solvent within the experimental accuracy (± 1% ) whereas the theological properties showed significant changes due, it is thought, to the thermal cycling and aging effects.

Abstract
The isobaric thermal expansion coefficient ( 0) was determined experimentally as a function of temperature for two non-Newtonian fluids: water solutions of CMC 7H4 at 5000 parts per million by weight (wppm) (purely viscous fluid) and AP-273 Separan at 2000 wppm (viscoelastic fluid). The temperature range was approximately 25-55° c theological flow curves were also measured during the experimental sequence. The expansion coefficients for the non-Newtonian fluids agreed with those for the pure water solvent within the experimental accuracy (± 1% ) whereas the theological properties showed significant changes due, it is thought, to the thermal cycling and aging effects.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
