    • An Explicit Scheme for the Calculation of Three-Dimensional Turbulent Boundary Layers 

      J. F. Nash (The American Society of Mechanical Engineers (ASME), 1972)
      An explicit finite-difference scheme is formulated for calculating the development of the incompressible turbulent boundary layer on an infinite yawed cylinder. The governing partial differential ...

    • Effects of Heat and Mass Transfer on Rayleigh-Taylor Instability 

      D. Y. Hsieh (The American Society of Mechanical Engineers (ASME), 1972)
      The effect on the interfacial gravity wave between two fluids is studied when there is a temperature gradient in the fluids. It is found that the thermal effect is closely related to the ...

    • On Flow Past a Supercavitating Cascade of Cambered Blades 

      C. C. Hsu (The American Society of Mechanical Engineers (ASME), 1972)
      A linearized theory for supercavitating flow through a cascade of cambered blades is developed. Numerical results illustrating various points of interest are presented.

    • Elastic and Creep Characteristics of a Class of Shell Closures With Constant Stress Ratio 

      A. E. Gemma; G. H. Rowe; R. J. Spahl (The American Society of Mechanical Engineers (ASME), 1961)
      A class of constant stress and constant stress ratio closures, σθ /σφ = K (1 < K < 2), was studied analytically. One type with the ratio K = 4/3 was investigated experimentally both ...

    • The Channel Flow of a Density-Stratified Fluid About Immersed Bodies 

      J. V. Droughton; C. F. Chen (The American Society of Mechanical Engineers (ASME), 1972)
      The flow of a density-stratified fluid about symmetric towed bodies was investigated both experimentally and theoretically. A cylinder and a slender body were towed through a linearly stratified ...

    • An Experimental Study of Rectilinear Jet-Flap Cascades 

      T. J. Landsberg; E. Krasnoff (The American Society of Mechanical Engineers (ASME), 1972)
      The performance of two-dimensional jet-flap cascades is determined experimentally. Stream deflection angles are presented as a function of the ratio of jet to mainstream momentum flux at chord ...

    • Two-Dimensional Diffuser Performance With Subsonic, Two-Phase, Air–Water Flow 

      J. E. Hench; J. P. Johnston (The American Society of Mechanical Engineers (ASME), 1972)
      The pressure recovery performance of straight-wall, two-dimensional diffusers with air–water mixtures has been investigated, and their behavior as a function of gas volume flow ratio and diffuser ...

    • The Kinetic and Thermal Expansion of Vapor Bubbles 

      D. C. Gibson (The American Society of Mechanical Engineers (ASME), 1972)
      The spherical expansion of vapor bubbles due to the application of either a thermal or a kinetic impulse is examined. There appears to be a wide range of initial and ambient conditions for ...

    • Addition of Heated Solid Particles to a Gas Flowing in a Pipe 

      G. Rudinger (The American Society of Mechanical Engineers (ASME), 1972)
      A number of processes, such as pneumatic conveying of powdered materials through ducts, feed lines for powdered rocket fuels, or certain flow processes in air-augmented solid-propellant rockets, ...
