Abstract: Smouldering combustion is a slow, low-temperature form of combustion that is used to improve soil health. Extensive research has yet to be completed about smouldering liquid hydrocarbons in a stationary porous medium such as coal tar in sand. This study examined heat transfer in sand under simulated smouldering combustion conditions. The Thermal Constants Analyser was used to measure the thermal conductivity, thermal diffusivity and specific heat of sand at heightened temperatures using the Transient Plane Source (TPS) method. Knowing these values will help to model the sustainable process of smouldering combustion in liquid fuel in the future.
