Effect of the choice of boundary conditions on modelling ambient to soil heat transfer near a buried pipeline

A new analytical model for short vertical ground heat exchangers with Neumann and Robin boundary conditions on ground surface

“…As a Dirichlet boundary condition might fail to model a real ground surface boundary condition, researchers employed the energy balance equation to describe the heat exchange between ground surface and surface air in numerical models [14][15][16][17][18][19][20].…”

Theoretical and applied aspects of using a thermal pump effect in gas pipeline systems

“…The effect of boundary temperature conditions on the heat exchange between the ground body and the underground pipeline is considered in [9]. One and two-dimensional models were used to calculate thermal conductivity.…”

Simulation and analysis of buried pipe heat transfer performance under leakage state

“…Kayaci and Demir [20] analyzed relationship between heat exchanger parameters of buried pipe and the soil temperature. Oosterkamp et al [21] examined soil surface boundary condition effects on calculation of heat transfer around the underground pipelines. The soil temperature, radiation balance on soil surface, together with the weather factors, were measured.…”
