Induction Heated Jacket Roll for High Temperature Calender

2DEG-HEATED AlGaN/GaN MICRO-HOTPLATES FOR HIGH-TEMPERATURE CHEMICAL SENSING MICROSYSTEMS

Fully-suspended AlGaN/GaN micro-hotplates that leverage self-heating of the two-dimensional electron gas (2DEG) have been modeled, micro-fabricated, and characterized at elevated ambient temperatures (from 25°C to 600°C in air). An input power of ~75 mW heated the micro-hotplates to approximately 270°C from 25°C ambient conditions. In addition, finite element analysis (FEA) showed high-temperat...

Temperature M easurements of Laser Heated Cavities

The heating of small cavities with pulsed laser or particle beams makes it possible to study phenomena of high-temperature radiation hydrodynamics and the state of matter at very high pressure, i.e. the physics of stars, for the first time in the laboratory [1], In this note we report preliminary results of temperature measurements made with gold cavities irradiated by 60-100 J/300 ps pulses fr...

Performance Improvement of a Slotted Solid Rotor Induction Motor with High Temperature Superconder Coating

This paper analyzes an induction motor with high temperature superconducter (HTS) coated slotted solid rotor. By slotting the solid rotor, the electromagnetic torque near synchronous speed will increase but the starting torque will decrease. To improve starting torque, rotor slots are coated with HTS materials. Using HTS material vary the rotor resistance to great extends in starting step and t...

Temperature structure functions for air flow over moderately heated ground

We study temperature structure functions of second, fourth, and sixth orders at heights of up to 2 m above the ground in moderately heated atmosphere. Most of the data come from measurements over salt flats of the Utah desert, with well-defined wind direction and uniform temperature boundary conditions. As in high-Rayleigh-number convection in a closed container, a thermal boundary layer develo...
