Combustion of N-Decane+air Mixtures To Investigate Laminar Burning Velocity Measurements At Elevated Temperatures

Measurement of Ultrasonic Velocity and Attenuation at Elevated Temperatures

Ultrasonic non-destructive testing is a sensitive tool not only for defect detection and evaluation in plant components and structures, but also to characterise microstructural features and for evaluation of mechanical properties. Even though, it provides high sensitivity and reliability for such measurements and very versatile to use at ambient temperatures, the technique fails when it is exte...

THE DEFORMATION BEHAVIOR OF AZ31 MAGNESIUM ALLOY AT ELEVATED TEMPERATURES

AZ31 magnesium alloy is considered as a promising alloy in various applications and industries. Furthermore, to design a proper hot working process (rolling, forging and extrusion), the assessment of hot working behaviour of the alloy is necessary. Accordingly, the hot deformation behaviour of AZ31 alloy was studied through hot compression testing method This was carried out in a wide range of ...

Laminar burning velocity of natural gas/syngas-air mixture

This study suggests the equimolar mixture of Natural Gas (100% CH4) and Synthesis Gas (40% H2 + 40% CO + 20% CO2) as an alternative to reduce hydrocarbons consumption and reduce pollutant emissions. As a key parameter to characterize this combustible mixture, the laminar burning velocity was studied based on numerical simulations and experimental measurements in fl ames generated using a contou...

Elastic Moduli Measurements at Elevated Temperatures using Ultrasonic Waveguide Embodiments

A measurement method is described here using a waveguide based technique with special modifications to the end of the waveguide in order to obtain reliable reflected ultrasonic signals from the end of the waveguide that is inside a heating chamber. The interpretation of the reflected signals leading to a quantitative measurement of moduli of the waveguide material i.e. Young‟s (E) and shear (G)...
