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 is effective. Then makes numerical solution
on the heat transfer of a fully rating well. This paper also studies on the influence of inlet
temperature and fluid flux of the heat transfer of SCW system. The results may provide guidance
for the design of SCW systems.
Key words: standing column well, heat and mass transfer, numerical simulation
