Thermal modeling of thermally isolated microplates
SPIE Proceedings, 2008In this paper we present an efficient method to calculate the thermal conductance in a thermally isolated microplate, connected to the substrate by two thin arms. The method can be applied to uncooled microbolometer pixels which in general, incorporate a thermally isolated microplate. The model approximates the microplate as a two-region slab, where

Electrical arcs and, more generally thermal plasmas, are widely used in many applications and the understanding or the improvement of the corresponding processes or systems, often requires precise modelling of the plasma. We present, here, a double approach to thermal plasma modelling, which combines the scientific procedure with an engineering point ...

AbstractThermal modelling of spacecraft requires approaches which can handle dominant radiative heat transfers and many special thermal control components. Present network‐type thermal analysers allow simulation, especially for components with rectangular geometries, but at the expense of considerable awkwardness and much error‐prone manual input.

Model calculations are made to obtain for certain load cases information on the thermal behavior of a telescope, or a telescope and its enclosure or of a specific structural component. The temperatures predicted from model calculations are used for design and/or operational purposes.

The TACOM Thermal Image Model (TTIM) will be described in some detail in this paper. This model maps a target/background scene radiance map pixel by pixel into an image as seen through a thermal imaging sensor. The development of TTIM was motivated by a need to analyze the thermal signatures of current and concept combat and tactical vehicles. A number

Thermal Modeling for High Thermal Conductivity Thermal Ground Planes
Volume 2: Heat Transfer Enhancement for Practical Applications; Fire and Combustion; Multi-Phase Systems; Heat Transfer in Electronic Equipment; Low Temperature Heat Transfer; Computational Heat Transfer, 2012Thermal ground planes (TGPs) are flat, thin (external thickness of 2 mm) heat pipes which utilize two-phase cooling. The goal is to utilize TGPs as thermal spreaders in a variety of microelectronic cooling applications. TGPs are novel high-performance, integrated systems able to operate at a high power density with a reduced weight and temperature ...

The Infrared signature of a vehicle is dependent on its surroundings in two ways. First, the vehicle image perceived in an IR scene is directly related to the thermal contrast between the vehicle and its physical environment. Second, the vehicle surface temperature is determined, in part, by the energy exchange at its boundaries which includes the ...

The study of Earth as an object whose history can be understood by application of physical laws dates back 200 years. This tradition is, however, rife with missteps related to as yet undiscovered physics or fundamentally incorrect assumptions. While the former is unavoidable, the latter amounts to self-inflicted wounds that may have forestalled ...

High-precision compact-thermal models
IEEE Transactions on Components and Packaging Technologies, 2005This paper is a step towards building a more complete theory of compact thermal models, in which their common structure is highlighted and hence the sources of errors inevitably present in any compact model clearly revealed. This approach is further extended in order to propose an original approach to attain any desired level of precision.
