superconducting materials are capable of trapping extremely high magnetic fields. this property and meissner effect of superconductors causes a levitation force between bulk superconductors and a permanent magnet (pm). this levitation force has possible industrial applications such as permanent magnet guideways (pmg). because of the high price of permanent magnets, the optimization of pmg desig...
Abstract Cracking property and brittleness are critically important to the drillability of injection production wells enhanced geothermal systems. This paper is devoted evaluating cracking Gonghe granite under high-temperature true triaxial compression conditions through a series laboratory tests. Thermal–mechanical coupled tests were conducted on samples four representative temperatures (20 °C...
Gas sensors with high sensitivity at and below room temperature, especially below freezing temperature, have been expected for practical application. The lower working temperature of gas sensor is better for the manufacturability, security and environmental protection. Herein, we propose a H2S gas sensor with high sensitivity at and below room temperature, even as low as -30 °C, based on Cu2O/C...
Rocket plume temperature distribution plays an important role on the heat transfer analysis of launch carriers. Thus, a non-intrusive IR scanner is used in this paper to analyze the influence of spin motion on plume centerline temperature measurements of spinning solid-propellant rockets. Results show that the average error of temperature measurement is below 3.5% even with a 10% error of estim...
