the transient mathematical equations are addressed for the coupled heat and moisture transfer by taking account of moisture accumulation procedure . an analytical method by means of the transfer function is proposed to predict the transient distributions of temperature and moisture content at different interfaces in walls . a numerical analysis approach based on an efficient finite-difference method is developed to deal with the procedure of coupled heat and moisture transfer in a multilayer wall with nonlinear boundary conditions considered
建立了考慮濕積累過程的瞬態(tài)熱濕耦合模型，在方程中引入了濕積累項(xiàng)；發(fā)展了一種傳遞函數(shù)解析方法進(jìn)行墻體內(nèi)不同剖面處溫度和含濕量的動態(tài)預(yù)測；首次提出了一種基于有效有限差分法預(yù)測非線性邊界條件下多層多孔結(jié)構(gòu)內(nèi)的傳熱傳濕過程的數(shù)值分析方法，求解過程中考慮了瞬態(tài)邊界條件，從而避免了通常處理中由于邊界條件設(shè)定為常數(shù)而給計(jì)算帶來的誤差，對于多層結(jié)構(gòu)每一層物性參數(shù)的非連續(xù)性，則采用了有效的有限差分逼近處理。
