Results are presented for an experimental study of Taylor vortices and turbulence in the flow between a rotating inner cylinder and both concentric and eccentric stationary outer cylinders. The results include: 1). measurement of the critical speed for onset of Taylor vortices as function of the eccentricity of the cylinders, 2). visual study of the flow up to a Reynolds number of 40,000, 3). measurement of the friction factor for the flow up to a Reynolds number of number of 40,000, 4). study of the effect of axial flow on the critical speed for onset of Taylor vortices. 5). preparation of design charts for calculating friction loss in concentric and eccentric journal bearings, operating in super-laminar flow regime.--Author.

The major objectives of the study were to determine the effects of variable injection angle and mass flow on heat transfer and flow characteristics in a vortex field confined in a centrally heated cylindrical tube, and to evaluate hot-wire probe techniques in similar conditions. Maximum vortex strength and heat transfer were generated at a 35 degree injection angle and produced a film heat transfer coefficient 2.3 times greater than that for axial flow at the same mass flow. Hot-wire results correlated reasonably well in similar flow conditions and indicated future possibilities in arc-stabilization studies. (Author).

An experimental investigation into the gas dynamics of a jet-driven vortex tube for application of a cavity nuclear reactor to rocket propulsion has shown that viscous retardation of the vortex motion is severe, because of a high level of turbulence near the periphery. Based on the experience gained in this study, it is estimated that the achievement of vortex strengths sufficient for practical application will require the use of small diameter tubes with appreciable expenditure of power for recirculation of the gas. The effect of the high degree of turbulence on the separation process near the periphery remains to be determined. The independent variables which were found to influence the vortex strength significantly for a given gas and temperature condition are the tube diameter, the mass flow rate per unit tube length, the injection velocity, and the wall pressure. Estimates of the degree of turbulence in vortex flow have been made from data on the variation in tangential velocity with radius. Virtual (total) viscosities near the periphery ranged from 30 to 700 times the molecular viscosity for tangential Reynolds numbers of from 4 x 10/sup 4/ to 2 x l0/sup 6/. Measurements of the position of the mole- fraction peak for separation of helium and a heavy vapor agreed with the theory for laminar flow. This suggests that near the center of the vortex tube where the peak developed the radial density gradient was sufficiently strong to suppress turbulence. It is concluded that the vortex reactor concept appears promising for application to nuclear rocket propulsion provided a satisfactory method can be devised for recirculation of the large excess mass flow required to maintain the vortex strength, and if turbulence does not appreciably limit the separation process. A separation experiment at elevated temperature appears to be the next logical step in the research program. (auth).
