| Abstract: | A mathematical model of the mass and heat transfer in the Standing Column Well (SCW) system is established and studied by means of numerical solution in this paper.Comparing the numerical solution results with test data shows that the mathematical model and numerical solution method established in this paper can reasonably describe the characters of heat and mass transfer in geothermal heat exchangers of the SCW system no matter there is seepage in the well wall or not.The results of numerical solution can meet requirements for engineering applications. |
