First-order fluid

First-order fluid

A first-order fluid is another name for a power-law fluid with exponential dependence of viscosity on temperature.

:mu_{operatorname{eff(dot gamma, T) = mu_0 {dot gamma}^{n-1} exp (-bT)

where dot gamma is the shear rate, "T" is temperature and mu_0, "n" and "b" are coefficients.

The model can be re-written as:mu_{operatorname{eff(dot gamma, T) = exp left( A_0 + A_1 ln(dot gamma) + A_2 T ight)
