Critical dynamics of thermal conductivity at the normal-superconducting transition
Some 15 years after the discovery of the cuprate superconductors, many tantalizing puzzles remain, particularly with regards to ground-state and possible quantum critical properties with varied doping. It has been difficult to disentangle consistent analyses faithful to experiment from the zoo of microscopic theories and models. In contrast, there have been notable successes in understanding th...
متن کاملTransport Processes and Thermal Conductivity near the Critical Temperature
— Near magnetic phase transitions a strong interaction between critical fluctuations in the magnetic spin system and the phonon heat carriers can lead to a phonon scattering that has a marked effect on the lattice thermal conductivity. By applying a large enough magnetic field to impose a ferromagnetic order on the spins, thereby eliminating the critical fluctuations, the phonon scattering by t...

~~'he t hermal conductivity of CO 2 has been m.easured in a coaxia l cyl inder cell as a fu nctIO n of pressure over a range of t emperatures from 3.66 to 75.26 °C. P ar Licular attention was given to t he measurement s from 1 to 9 deg C above t he cri tical t emperature at pressures closely spaced to i nclude t he crit ical density. The t hermal co ndu ctivity of CO2(0) near t he cri tical poi...
متن کاملTransport Properties of Refrigerant Mixtures: Thermal Conductivity
In the present work, the integral equations method is used to calculate transport properties of polar fluids. For this goal, we use the Stockmayer potential and examine theoretically the thermal conductivity of several refrigerant mixtures such as R125+R134a, R125+R32, R125+R152a, R134a+R32, R152a+R32, R134a+R143a, and R125+R143a. We solve numerically the Ornstein-Zernike (OZ) equation usin...
متن کاملThermal Conductivity of Nanofluids
Nanofluids are suspensions of nanoparticles in base fluids, a new challenge for thermal sciences provided by nanotechnology. Nanofluids have unique features different from conventional solid-liquid mixtures in which mm or μm sized particles of metals and non-metals are dispersed. Due to their excellent characteristics, nanofluids find wide applications in enhancing heat transfer. Research work ...
