Transportation of indoor double diffusive mixed convection coupled with diffusion in solid walls

Numerically studies the indoor double diffusive mixed convection process coupled with heat and mass diffusion in solid walls. Simultaneously solves the corresponding momentum conservation equation，energy conservation equation，pollutant mass species conservation equation，and heat-function and mass-function equations across both fluid and solid regions. Analyses the influences of air supplying intensity，heat source intensity，pollutant source intensity and heat/mass diffusion characteristics of the wall on the indoor mixed convection in details. Adopts streamlines，heat-lines and mass-lines to represent real transportation routes of fluid，heat and pollutant both in solid walls and in building enclosure.
