Estimating the temperature of bulk explosives in landmines is necessary for an optimally designed Nuclear Quadrupole Resonance explosive detection system, a technology that holds promise for mine detection system false alarm reduction. Pursuant to this objective it is necessary to study the heat conduction and temperature profiles of buried mines over diurnal cycles.Finite element models are constructed and a thermal analysis is performed for buried SI M-25 (landmine simulant) and VS 1.6 anti -tank landmine. The Ansys finite element software is used to create, to solve and to post -process the thermal models. Transient thermal analyses with various boundary conditions and simple soil models are performed. We report on the bulk explosive temperature, thermal flux and thermal gradients for these mine models over diurnal cycles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
