【摘要】 建立了通风管基础的传热数学模型,并在此模型基础上采用有限单元法对保温层和通风管基础进行数值模拟分析。通过对保温材料在冻融循环条件下保温效果的数值模拟,得出通风管基础中保温层与通风管应当结合使用,且保温层应尽量选用密度相对较大的EPS保温板的结论。更多还原

【Abstract】 In this paper,a heat transfer model was established and the numerical simulation between insulation and ventilated foundation was analyzed by FEM.Learned from the results of numerical simulation of the insulating effect,which under the condition of cycling of freezing and thawing,conclusions have been drawn that the insulation and ducts should be combined to use and the insulating layer should choosing the EPS with higher density which contrasts to others.更多还原
