The Subject

Ferrofluids have been the subject of great interest in engineering because of their unique flow characteristics under magnetic fields (Rosensweig, 1987). However, there are limited experiments which show the potential of ferrofluids to undergo controlled changes in thermal conductivity (Philip et al., 2008) under magnetic fields. The purpose of this experiment is to investigate thermal transport in ferrofluids. A test apparatus was designed and the thermal resistance of a commercially available ferromagnetic fluid within a test cell was measured as a function of the applied magnetic field.

AbstractThe present research is designed to examine the dynamic of the quantum computational speed in a nanowire system through the orthogonality speed when three distinct types of magnetic fields are applied: the strong magnetic field, the weak magnetic field, and no magnetic field. Moreover, we investigate the action of the magnetic fields, the spin-orbit coupling, and the system’s initial states on the orthogonality speed. The observed results reveal that a substantial correlation between the intensity of the spin-orbit coupling and the dynamics of the orthogonality speed, where the orthogonality speed decreasing as the spin-orbit coupling increases. Furthermore, the initial states of the nanowire system are critical for regulating the speed of transmuting the information and computations.

The Magnetic Field

Heat is generated in superconducting windings whenever the magnetic field changes. During these transient periods, the current carrying capability of the superconductor is limited by the temperature distribution inside the winding, especially in epoxy-impregnated winding composites that have limited thermal conductance. A finite-difference transient thermal analysis of a superconducting winding composite is presented. The analysis is employed to predict the critical current of a cylindrical coil and a modular racetrack winding under linear ramping of the magnetic field, when eddy current losses and hysteresis losses prevail. The dependence of these losses on the magnetic field and temperature is properly accounted for. The analytical predictions are compared to experimental data and the agreement is excellent.
