Syntax

Viscosity [{of} SpeciesName] = Curing_Foam [Mu_A = mu_a | T_Mu = t_mu | N_Mu = n_mu | E_Mu = e_mu | R = r | Ksi_C = ksi_c | M_Ksi_C = m_ksi_c | Extent_Subindex = extent_subindex]

Scope

Aria Material

Summary

For a curing foam with gas volume fraction \phi_g and extent of reaction \xi the viscosity is given by

\mu\left(\xi, \phi_g, T\right)= \mu_{a} \left(1 - \dfrac{T}{T_{\mu}} \right) \left(1 - \left(\frac{\xi}{\xi_c}\right)^m \right)^{n_{\mu}} e^{E_\mu/RT} e^{\phi_g/\left(1 - \phi_g\right)}

where T is the temperature and the default model parameters are \mu_{a} = 800.93, T_{\mu} = 364.059, n_{\mu} = -4/3, E_{\mu} = 0.0, R = 1.987, and \xi_c = 0.45. NOTE: The gas volume fraction is assumed to be a SPECIES field with the subindex provided by the VFRAC_SUBINDEX parameter. Likewise, the extent of reaction field is assumed to be a SPECIES field with the subindex provided by the EXTENT_SUBINDEX parameter.
