Heat Transfer Incropera Solution IHT Software
this report describes the design and development of an automated system which will permit the physical characterization of the heat transfer properties of a substrate, and more generally of a solid material. the system uses a liquid to test a solid material, i.e. it uses the solid material as a heat sink. the results of this study will be used to determine the temperature of a solid substrate for various applications in microelectronics.

flexible graphene is a promising material for the construction of electronic devices. in this study, we investigate the use of graphene in the production of a thermoelectric heat engine. we use a green's function approach to simulate the transport of charge carriers in the graphene. we also account for the effect of phonons, which are the main carriers of thermal energy in graphene. this study is the first investigation of the use of graphene for the construction of a thermoelectric heat engine.
heating and melting of solid materials are important processes in a variety of industrial and scientific applications. a complete understanding of such processes requires an accurate description of the temperature-dependent properties of the solid materials being heated. the melting of an ultrathin metal film is a good example of a solid material that exhibits unique temperature-dependent properties due to its high density and small thickness. a precise characterization of these properties would be beneficial for a number of applications, such as for the prediction of the melting temperature of ultrathin metallic films.
in the eighteenth century, the theory of heat transfer was extended to include the transfer of matter and energy in both directions between two different media. this led to the concept of internal energy. the internal energy of a substance is equal to the amount of energy that it absorbs from the surrounding environment (inertia) plus the amount of energy that it releases (thermal heat).
