Thermal convection in the porous methane-soaked regolith of Titan: Investigation of stability

Titan is the only body, other than the Earth where liquid is present on the surface. In the present work we consider behavior of methane in the pores of Titanʹs regolith. Using numerical model we investigate quantitative conditions necessary for the onset of convection. We have found that the methane convection in Titanʹs regolith is possible. It can be expected in regions where the regolith has sufficiently high porosity, independently of the geothermal heat flux.
