Design of nozzles for partly ionized gases
An analytic expression is obtained for the speed of sound in a partly ionized gas under certain conditions. The method of characteristics is adapted to use this information for the solution of the compressible gas flow ...
Electrical properties of argon gas emerging from a plasma jet
Argon gas, which had been partly ionized by an electric arc with an enthalpy input in the order of 104 BTU/lbm was expanded through a supersonic wind tunnel nozzle. It was found to contain residual positive ions in excess ...
Primary creep of polycrystalline copper and determination of the activation volume
Creep experiments were conducted using high-purity polycrystalline copper at 78°K and 300°K. The results arc analyzed in terms of an intersection mechanism between the moving and forest dislocations. The activation volume ...
Stacking faults in platinum
Determination by X-ray techniques of stacking-fault densities in platinum was attempted. Heavily deformed platinum was annealed under varying conditions of temperature and time. The X-ray method used for measuring ...
