SUMMARY

The discussion focuses on finding a formula to describe the behavior of a viscous and compressible fluid, particularly in relation to density variability. The user seeks a generic starting point and mentions non-Newtonian fluids, which do not fully address the need for a pressure factor. Key resources provided include a specific formula from a Springer article and a comprehensive textbook by Richard Fitzpatrick. These sources serve as foundational references for understanding fluid viscosity and compressibility.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Familiarity with non-Newtonian fluid behavior
  • Knowledge of viscosity and compressibility concepts
  • Basic mathematical skills for applying fluid formulas
NEXT STEPS
  • Research the specific formula for compressible viscous fluids from the Springer article
  • Study the textbook by Richard Fitzpatrick for in-depth fluid mechanics
  • Explore the Wikipedia pages on viscosity and volume contraction for foundational knowledge
  • Investigate the application of pressure factors in fluid dynamics
USEFUL FOR

Researchers, engineers, and students in fluid mechanics, particularly those focusing on the properties of viscous and compressible fluids.

Sorry if this is to basic of a question. I'm trying to find a formula that will describe a viscous, but compressible fluid. This would just be a generic formula as a starting point. I'm trying to describe the variability of densities through this fluid. The closest thing I can find is a non Newtonian fluid, that decribes how stress in an area dissipates through the fluid. But this doesn't really fit what I'm trying to do since i need a "pressure" factor.

You could start with the Wikipedia pages on the subject and the links there:
https://en.wikipedia.org/wiki/Viscosity
https://en.wikipedia.org/wiki/Volume_contraction

If they do not contain what you're looking for, then you get at least a couple of terms you can use for a Google search.

Here's what I've found as THE formula (see Summary):

or an entire book about it (Author's page, Richard Fitzpatrick, Austin TX):
