We report a model that can be used to calculate superconducting transition temperature of a transition-edge sensor (TES), which is either a normal metal–superconductor–normal metal trilayer or a normal metal–superconductor bilayer. The model allows the $T_{C}$ estimation of a trilayer when the normal metals at the bottom and at the top are different. Furthermore, the model includes the spin flip...
In the present study, a finite element analysis of conjugate heat transfer problem inside a cavity with a heat-generating conducting body, where constant heat flux is generated, is conducted. A conduction heat transfer problem inside the solid body is automatically coupled with natural convection inside the cavity by using a finite element formulation. A finite element formulation based on SIMPLE...
In A finite element code based on P2P1 tetra element has been developed for the large eddy simulation (LES) of turbulent flows around a complex geometry. Fractional 4-step algorithm is employed to obtain time accurate solution since it is less expensive than the integrated formulation, in which the velocity and pressure fields are solved at the same time. Crank-Nicolson method is used for second order...
This paper presents an analytical design method of indirect full digital controller with a simple structure for three-phase inverter system. Most of conventional researches on the analytical design of controller have been studied about the structure of continuous-time controller, and so the final implementation of full digital controller for industrial application was complicate and anyway based on...
This paper calculates the single conductor corona inception voltage and corona inception electric field based on a corona inception voltage criterion. The calculated results agree with the results of Peek formula well. At the same time this paper analyzes the effect of air pressure, temperature and height above sea level on the corona inception voltage and corona inception electric field. It is found...
