【摘要】 在利用有限元法求解二维稳定温度场的基础之上,推求了渗流影响下的二维稳定温度场的有限元计算格式,编写相应程序计算温度场内各节点温度值,最后运用程序对一简单工程算例进行有限元法分析。结果表明,一般情况下,当渗透系数K≤10-9m/s的时候,可以不考虑渗流对温度的影响;但是当渗透系数K>10-9m/s的时候,就必须考虑渗流对温度的影响。更多还原

【Abstract】 Based on the finite element method for solving two_dimensional steady temperature field,the finite element formulations of two_dimensional steady temperature field considering the seepage effect are derived and the corresponding programs are developed to compute the node temperature in temperature filed.Finally,the finite element analysis of a case study is illustrated.It has been shown that when permeability coefficient ≤10^-9,seepage effect may not be considered for temperature under normal conditions,but when permeability coefficient>10^-9,seepage effect should be considered.更多还原
