What are typical values for 'K' in the Ostwald model for non-Newtonian fluids?

SUMMARY

The discussion focuses on the typical values of 'K' in the Ostwald model for non-Newtonian fluids, specifically for strain-hardening fluid flow. Participants noted that 'K' values generally range from 1 to 10, with some specific references indicating values between 1 and 2. Key resources provided include a PDF from Gazi University and an article from IOPscience, which both offer insights into these values. This information is crucial for modeling shear force on a wall in fluid dynamics applications.

PREREQUISITES
  • Understanding of the Ostwald model for non-Newtonian fluids
  • Familiarity with strain-hardening fluid behavior
  • Basic knowledge of shear force calculations
  • Access to fluid dynamics literature and resources
NEXT STEPS
  • Research the Ostwald model in detail, focusing on its application to non-Newtonian fluids
  • Explore fluid dynamics textbooks for comprehensive tables of 'K' values
  • Investigate the impact of different materials on 'K' values in the Ostwald model
  • Learn about alternative models for non-Newtonian fluids, such as the Bingham plastic model
USEFUL FOR

Fluid dynamics engineers, researchers in material science, and anyone involved in modeling non-Newtonian fluid behavior will benefit from this discussion.

I need to make a simple model of a strain-hardening fluid flow, basically to find shear force on a wall. I'm looking at the Ostwald model
http://www.answers.com/topic/power-law-fluid

but I can't find any values for "K" for any material. I don't really care too much what material I'm looking at, I just want to at least get an idea of what it typically looks like. Does anyone know of any resource with tables of some K values?
