The Thomson Effect and the Ideal Equation on Thermoelectric Coolers
The formulation of the classical basic equations for a thermoelectric cooler from the Thomson relations to the non-linear differential equation with Onsager’s reciprocal relations was performed to basically study the Thomson effect in conjunction with the ideal equation. The ideal equation is obtained when the Thomson coefficient is assumed to be zero. The exact solutions derived for a commerci...
متن کاملImproved Thermoelectric Cooling Based on the Thomson Effect
Traditional thermoelectric cooling relies on the Peltier effect which produces a temperature drop limited by the figure of merit, zT. This cooling limit is not required from classical thermodynamics but can be traced to problems of thermoelectric compatibility. Alternatively, if a thermoelectric cooler can be designed to achieve full thermoelectric compatibility, lower temperature can be achiev...
متن کاملThe Thomson Effect and Thermal Conduction in Metals.
The Thomson Eflect.-In these PROCZZDINGS for March, 1920, is a paper in which I undertook to account for the Thomson effect values, as found by Bridgman for many metals, in accordance with the hypothesis of dual electric conduction. Using data obtained by the methods of that paper, I was able. as I stated at the Washington meeting of the National Academy in April, 1920, to account quantitativel...
متن کاملJohn Thomson
one whose clinical acumen, painstaking and accurate observations and valuable writings had gained for him a reputation which was world-wide and which added a lustre to British Medicine. John Thomson was born in Edinburgh in 1856, and, after receiving his education at the Academy and University, he studied in London, Berlin and Vienna. His interest was early directed towards diseases of children...
متن کاملQuantum Joule-Thomson effect in a saturated homogeneous Bose gas.
We study the thermodynamics of Bose-Einstein condensation in a weakly interacting quasihomogeneous atomic gas, prepared in an optical-box trap. We characterize the critical point for condensation and observe saturation of the thermal component in a partially condensed cloud, in agreement with Einstein's textbook picture of a purely statistical phase transition. Finally, we observe the quantum J...
