Numerical Heat Transfer Simulation on Breathing-Type Glass Double Facade

On the principle of energy balance on interface, a 3D mathematic model for simulating the heat heat transfer process in glass double facades is presented and solved by coupling the conductive and radiative heat transfer in solid with the viscosity fluild . Under the typical meteorologic condition of north china, the heat insulation in the summer、air exchange and ventilation、 dewing preven- tion and heat preservation in the winter were discussed. The conclusion drawn in the paper will promote the development...
