temperature driven flow is referred to as thermosiphon, and may cause considerable increase in the heat transport from groundwater … filled boreholes. The thermosiphon effect is connected to thermal response tests, where the effective ground thermal … conductivity is enhanced by this convective transport. Strong thermosiphon effects have frequently been observed in field …
