Thermal Interaction of Inert Additives in Energetic Materials
… is often thought to be proportional to the bulk thermal diffusivity of the material. However, the inclusion of insulating inert particles in energetic materials has shown burning rate enhancement in certain cases. Flame front corrugation that increases the reaction front area observed at micron …

Development and evaluation of a thermal model for haptic interfaces
The thermal interaction between the skin and an object is influenced by the thermal properties and initial temperatures of the skin and object, and by the contact force and surface roughness of the contact surfaces. This thermal interaction is modeled in this research which characterizes the …

Thermal analysis of power hybrid microelectronic packages
… a simplified nondimensional approach for the thermal analysis of power hybrid circuits is presented. The new technique uses only the metallization and the substrate as layers and represents everything below the substrate by an external thermal resistance (expressed as an equivalent convective …

Thermal modeling of hybrid microelectronics
… is reduced, the power density increases and thermal interaction between heat-producing devices becomes significant. A nondimensional model is developed to investigate the effects of heat source interaction on a substrate. The results predict the maximum temperature created by a device for a …

Thermal sustainability of low-temperature geothermal energy systems: System interactions and environmental impacts.
… Due to their good efficiency, the use of geothermal energy is often encouraged; however, two issues arise in the long-term use of ground for thermal purposes: the sustainability and impact of these systems on the environment. Studies show the potential of the geothermal heat exchangers for …

Heat transfer from molten materials to liquids
… A series of experiments to investigate the thermal interaction between molten metals (aluminium, lead and tin) and sub-cooled water were conducted. The cooling rates of the molten materials under conditions of flooding were measured with a high speed-thermocouple and recorded with a …

Investigation of pressure-tube and calandria-tube deformation following a single channel blockage event in ACR-700
… the PT. The hot spot caused by the molten Zry/PT interaction may cause PT/CT failure due to localized plastic strains. Failure of the PT/CT results in depressurization of the primary system, which triggers a reactor scram, after which the decay heat is removed via reflooding, thus PT/CT rupture …

Thermal Performance Enhancement of a Crossflow PCM-to air and liquid Heat Exchanger
… distribution, fin density, and PCM type on the thermal performance of a single-slab PCM-HEX. Study 2 employs the findings of Study 1 and strategically employs multiple PCMs to enhance the thermal performance of the five-slab PCM-HEX. Computational fluid dynamics (CFD) simulations are employed to …
