The effect of ultra-high pressure on the thermal emf of a
chromelialumel thermocouple is investigated using an indirect
method which does not require a direct knowledge of the temperature
of the pressurized junction. The unknown temperature is written
parametrically as a function of a directly measured quantity, the
electrical power...
The Seebeck coefficient is examined in the high temperature limit, using an approach based on a grand partition function containing Hubbard Hamiltonian interaction terms. Although the carriers of interest occupy localized Wannier states, this work is prefaced by the case of delocalized Bloch states, which is examined using Boltzmann transport,...
The topic of this thesis is to discuss an
investigation made for a fluid velocity measuring device.
The OSU thermal hydraulic testing facility is interested
in using a small probe to measure fluid velocities in the
annular region of a model nuclear reactor vessel. A
heater with a thermocouple embedded...
