摘要
以地源热泵地埋管非稳态随机传热模型为研究对象,将地埋管周围土壤温度场的随机性作为研究的重点,利用数值解法中的有限差分法,对地源热泵地埋管二维非稳态随机传热模型建立了古典隐式格式的差分方程。从而能够求解出地埋管周围土壤温度场的数值解,为进一步分析非稳态随机传热模型的随机温度场打下基础。
This paper studied unstable and stochastic heat transfer model of buried pipe in GSHP,used the randomness of soil temperature field around buried pipe as the key point,and established two-dimensional unsteady random heat transfer model’s implicit difference scheme of classical differential equations by using the finite difference numerical method;so we could get numerical solutions of soil temperature field around buried pipe and lay the foundation for further analysis of random temperature field of unsteady random heat transfer model.
