Аннотация

An analytical solution is developed for steady-state heat transfer from a buried circular pipe to greenhouse soil, modeled using a point source (logarithmic singularity). The source location differs from the pipe center. An approximate heat transfer condition on the soil surface is introduced, with negligible error in practice. Explicit equations are provided for soil temperature distribution, surface temperature, total heat flux from the pipe, and surface heat flux density. This approach addresses sustainable heating using secondary energy resources.
