摘要: Abstract In this paper, convective-conductive heat transfer processes between the all components of geothermal borehole exchanger (BHE) such as pipe-in, pipe-out and grout have been studied. A set coupled partial differential equations subjected to general initial boundary conditions are governed problem. Modified Homotopy perturbation method (MHPM) is a hybrid discrete Fourier Transform, spectral analysis Perturbation Method that developed in order solve systems. The results MHPM compared with numerical solution for validation and, furthermore, effectiveness accuracy applied shown.
