Abstract
Modelling heat migration in soils is of great interest in various civil and electrical engineering projects. Researchers have developed several analytical and numerical models to model heat migration in soils and their validity has been demonstrated by conducting conventional laboratory or field experiments. Though laboratory tests are inexpensive, quick and easy to perform, they lack simulation of the prototype conditions in terms of in-situ stresses. To overcome this, field tests, which are relatively costly, time consuming and difficult to perform, are found to be of immense help. In order to overcome these limitations, a geotechnical centrifuge can be used for studying heat migration in the soil mass. To demonstrate the utility of a geotechnical centrifuge for such studies, standard grade sand compacted to different states has been chosen. Using a line heat source, a thermal probe, thermal gradient has been imposed and migration of heat in the soil mass has been studied by recording its temperature as a function of time and radial distance. The study highlights utility of a geotechnical centrifuge in modelling heat transfer in the soil mass.
