【Objective】The wall design of Chinese solar greenhouses(CSG) is closely related to the inside air temperature.【Method】The temperatures in CSG were simulated for seventeen wall layer designs using Computational Fluid Dynamics(CFD). The brick wall or insulation layer thicknesses were changed in each of the seventeen designs with the total layered wall thickness( the thickness of the walls remained the same).The numerical models were validated in a previous study(Tong et al.,2009). The simulation domain includ...
