Detailed Description

template<int dim, typename number>
class MeltPoolDG::Evaporation::IncompressibleNewtonianFluidEvaporationMaterial< dim, number >

Class for the shear stress computation of an incompressible vapor/liquid mixture, where the velocity field is not divergence-free in the interfacial region. The intention is to correct the rate-of-deformation tensor to be nearly deviatoric.

It is assumed that the stress computes as follows

σ = -p * I + 2 * μ * (D - tr(D) * n⊗ n)

with the Cauchy stress tensor σ, the pressure p, the second-order identity tensor I, the dynamic viscosity μ, the rate-of-deformation tensor

D = 0.5 * (∇u + (∇u)^T),

the interfacial unit normal vector n and the dyadic product ⊗ .
