Abstract:
Parametric modeling of layer-configuration and heat-sink controlled temperature fields within layered materials is examined. This modeling is in terms of the heat-kernel solution to the heat conduction equation with the introduction of finite layers of varying thermal diffusivities and a negative thermal impulse, of the heat kernel form, for the introduction of singular heat-sink layers. This provides phenomenological parametric representations of temperature distributions within layered-material systems and can be utilized for their design and optimization for layer-configuration and heat-sink control of thermal transport. Results of prototype modeling of controlled heat transfer in layered-material systems are presented, demonstrating general aspects of parametric models for thermal analysis and simulation of heat-transfer control using layer configurations and embedded heat sinks.
