Abstract: The theory of rotating fluids is applied to the flow in the cyclone. The effects of radial instabilities in the boundary layers on the walls are discussed. The dynamics of the central core ...

Abstract: The symmetric vortex in a cylindrical cyclone with a flat bottom was studied with the aid of smoke, and was probed for the distribution of the velocity. The smoke studies revealed a laminar ...

Abstract: An analysis of the effects of pressure drop in the heat-exchange components of a Stirling cycle has been made and successfully applied to an experimental refrigerator. Data are presented for ...

Abstract: Experiments were performed on a piston-cylinder gas spring. Speed, cyclic mean pressure, gas, bore/stroke ratio, volume ratio, and internal extended surface geometry were varied. Hysteresis loss, ...

Abstract: A theoretical and experimental investigation examines the performance of thermal regenerators in which rapid flow cycling is accompanied by large pressure variations with time. This class of ...

Abstract: An approximate closed-form solution for the thermal performance of a Stirling-engine regenerator is derived. The solution is for sinusoidal mass flow rate and sinusoidal pressure variation with ...

Abstract: A mathematical model of Stirling-type engines has been developed. The complexity of the problem has been reduced by analyzing the various components of the engine (heat exchangers, regenerator, ...

Abstract: The phenomena of patchwise boiling are discussed, and the significant parameters restricting the growth of a boiling patch are analytically determined to be: (a) a high nucleate-boiling heat-transfer ...

Abstract: Pool-boiling experiments were performed in helium from high purity copper which had been exposed to various amounts of fast neutron radiation. The residual effects of the radiation influenced ...

Abstract: The paper considers the smallest size refrigeration plant likely to be required for liquid nitrogen cooled electric power transmission lines. Nitrogen, neon, hydrogen, and helium cycles are ...
