7.6.8.3.7. Mass_Diffusion_Energy_Transport

Syntax

Heat Conduction [{of} SpeciesName] = Mass_Diffusion_Energy_Transport

Scope

Aria Material

Summary

Mass diffusion model for energy transport

Description

Heat conduction is calculated as

${\bf{q}} = \rho_g D (h_{water(g)} \nabla Y_{water(g)} + h_{air(g)} \nabla Y_{air(g)})$

where $\rho_g$ is the gas phase density, $Y$ is the mass fraction, $D$ is the mass diffusivity and $h$ is the specific enthalpy. The subscripts $air(g)$ and $water(g)$ represent air and water in the gas phase.
