The planned International Facility for Antiproton and Ion Research (FAIR) will consist of a superconducting double-ring synchrotron offering ion beams of intensity increased by a factor of 100-1000 compared to the existing GSI accelerators. Materials close to the beam tube will be exposed to secondary radiation of neutrons, protons, and heavier particles, possibly limiting reliable function and...
Measurements of thermal conductivity with the heat flow meter, laser flash method, hot disk method and wire are compared on two kinds refractory materials: Insulating Boards Fireclay Bricks. Heat losses, humidity, anisotropy heterogeneity can explain variation in values obtained different techniques. If they taken into account analysis, discrepancy within 10% be found. The choice technique depe...
IMPROVING THE FIRE PERFORMANCE OF HIGH-RISE BUILDINGS’ FAÇADE WITH NANO-THERMAL INSULATING MATERIALS
Thermal insulation materials protects internal surface of the motor casing in contact with the hot produced gases, extreme turbulence flow and high pressure due to combustion propellant. Insulation Materials in the rocket motor covers the inner surface of the motor casing and protect the body against the damage caused by extreme and short-term heat, intense turbulent flow and high pressure. O...
The current multi-layer insulation used in the extravehicular mobility unit (EMU) will not be effective in the atmosphere of Mars due to the presence of interstitial gases. Alternative thermal insulation means have been subjected to preliminary evaluation by NASA to attempt to identify a material that will meet the target conductivity of 0.005 W/m-K. This study analyzes numerically the thermal ...
