Since energy and mass are exclusively transferred by diffusion across the fluid-solid interface, a no-slip boundary condition for the fluid flow is applied at the particle surface to prevent artificial convective transport into the particle ). The implemented conjugated heat and mass transfer model couples the diffusive boundary fluxes of heat and species mass between the fluid and solid domain of the interface. Due to the analogy of heat and mass transport, heat and species mass diffusion can be generally described as a diffusive flux ω of a scalar ϕ.
