【Abstract】 Zero equation model is applied in thermal environment simulation of large-space buildings.The characters of the model,such as high time sensitivity and less accuracy requirement, make it suitable for large-scale engineering problems.In addition,SUPG approach is introduced to discretize the advection term in order to suppress the numerical disperse.Finally the previous algorithm is verified by the practical application.更多还原
