| Abstract: | The heat transfer of a vertical borehole is discussed for geothermal heat exchangers.An explicit analytical solution is given in terms of the one-dimensional cylinder model.The solution of the simplified line-source model is compared with that of the cylinder model,and the limitation for its application has been determined.In comparison with the semi-infinite plate model,another approximate expression of the cylinder model has been obtained,which is simple and suited better to short times. |
